Grigor Dimitrov claims maiden ATP World Tour Finals title after overcoming stubborn David Goffin

8:48PM

The champion

Dimitrov's in tears! Goffin looks inconsolable. The pair embrace at the net. David Bowie's 'Heroes' rings around the O2. Dimitrov hugs every single member of his team. It's the biggest title of Dimitov's career, and what a brilliant final that was. 

8:48PM

Game, set and match! Dimitrov defeats Goffin 7-5, 4-6, 6-3 

Goffin misses an easy backhand; Dimitrov returns the favour with a simple forehand error. 15-15. Goffin then nets a forehand - 30-15. The Dimitrov camp can barely watch. A big unreturnable serve from Dimitrov makes it 40-15, which brings up two more match points. How's your never Grigor? Well, he just misses a forehand pass on the first one and it's 40-30. One more to go. And this time Dimitrov takes it as Goffin nets a backhand volley!

Grigor Dimitrov is the 2017 ATP World Tour Finals champion.  

8:43PM

Dimitrov* 7-5, 4-6, 5-3 Goffin (*next server) - Goffin saves three championship points and holds on!

Brilliant exchange with both men at the net ends with Dimitrov flicking away a backhand winner for 0-15. The Bulgarian then moves to 0-30 after a sensational chase down of a Goffin stop volley, and it's three match points at 0-40 when Dimitrov flicks away a backhand passing shot winner. The first two comes and goes as Goffin produces a backhand winner and then an ace. Third time lucky for Dimitrov? No, he tightens up and nets a very makeable forehand! Back to deuce. This is so tense.  Goffin takes the next two points, and clings on! He implores the crowd to make some noise, and on we go. 

Dimitrov, having missed three championship points, will now serve for the biggest title of his career. 

8:34PM

Dimitrov 7-5, 4-6, 5-2 Goffin* (*next server)

Dimitrov has not always been the best at closing out matches - witness his meltdown in Istanbul last year having been a set and 5-2 up - and so Goffin is still right in this match. 

The Bulgarian shows no signs of nerves here though, as he scores a straightforward hold to 15 . Goffin will now serve to stay in the final. 

8:32PM

Dimitrov* 7-5, 4-6, 4-2 Goffin (*next server) - Dimitrov breaks

Again Goffin sees a 30-0 lead quickly become 30-30, and suddenly Dimitrov's eyes light up. A tired looking forehand from the Belgian then hands his opponent a break point at 30-40. Can Dimitrov take this one? No, he can't. Again he's a little passive on a big point, and it's Goffin who steps up the aggression to force an error and cling on. But after a couple of missed game points, Goffin nets a backhand, and it's break point Dimitrov again. And this time he takes it! Goffin misses a backhand, and Dimitrov is two service holds away from the title. 

8:22PM

Dimitrov 7-5, 4-6, 3-2 Goffin* (*next server)

Blessed relief for Dimitrov as he scores a breezy love service hold. The pressure swings back to Goffin. 

8:20PM

Dimitrov* 7-5, 4-6, 2-2 Goffin (*next server)

Nothing's coming easy for either player at the moment, and Goffin sprays a forehand well wide for 30-30. A double fault then sees a game point come and go, and we're at deuce. Goffin does complete the hold moments later though, courtesy of a forehand winner and a missed Dimitrov backhand return. 

8:14PM

Dimitrov 7-5, 4-6, 2-1 Goffin* (*next server)

Goffin looks set to make inroads again on his opponent's serve when he scorches away a forehand to move up 0-15. Dimitrov slams the door shut though and claims the next four points to complete a hold to 15. 

8:11PM

Dimitrov* 7-5, 4-6, 1-1 Goffin (*next server) - Gofifn saves a break point and holds

Goffin looks by far the fresher of the two players, but Dimitrov is digging in, and he battles his way to 30-30 when his opponent makes a couple of errors. The Bulgarian then forces a break point at 30-40 after a stunning rally that has both men hurtling around the court and trying to break their rival's resistance. But chapeau Goffin, who saves the break point with a big first serve, and then nails a couple more big first serves to eke out a crucial service hold. 

8:07PM

Dimitrov 7-5, 4-6, 1-0 Goffin* (*next server) - Dimitrov saves four break points and holds

I'm sticking with my prediction of Dimitrov to win in three. Andrew Castle agrees with me; Tim Henman is going for Goffin. 

Goffin has the bit between his teeth at the moment, and he crunches a backhand return winner up the line to move up 15-40 and two break points. Dimitrov saves them both though - the first with an ace, the second with a conservative 93 mph first serve that rears off the line awkwardly and befuddles his opponent. A third break point then comes and goes, as Goffin snatches at a makeable first serve return. "Come on!" roars Dimitrov in celebration. Goffin is red lining at the moment though and forces another break point with a couple of sumptuous forehands. But again he wastes the opportunity, as he skews a backhand a few feet long. Goffin had the break on his racket there. Dimitrov eventually clings on and completes the hold, and that is a massive opportunity missed for Goffin. The Belgian was spraying winners and had his opponent on the ropes, but Dimitrov somehow found a way to get through it. 

Have we just witnessed another momentum shift in the match?

7:56PM

Dimitrov* 7-5, 4-6 Goffin (*next server) - Game and second set Goffin

No signs of nerves from Goffin. He closes out the set to love, and we're going the distance here. The set turned on a sixpence after that missed Dimitrov break point in the sixth game. 

Goffin has a Tour-best record for deciding sets in 2017 - 22 wins from 27 matches. 

7:51PM

Dimitrov 7-5, 4-5 Goffin* (*next server)

Wow, Goffin has the bit between his teeth now, and he absolutely leathers a forehand return winner for 15-30. Dimitrov responds with a sensational backhand half-volley up the line from the baseline to level things up at 30-30. The Bulgarian reels off the next two points to complete the hold. Goffin will now serve to take us into a decider. 

7:48PM

Dimitrov* 7-5, 3-5 Goffin (*next server)

Andrew Castle continuing to patronise the hell out of Goffin and is going on and on about his grey socks. He also says the first time he saw Goffin was against GB in the Davis Cup when 'Goffin was an unknown who had just played a couple of Challenger events'. He was the world No 16 at the time! 

Anyway, Goffin shows his mettle again here and grinds out a hold to 30. Dimitrov will now serve to stay in the second set. 

7:44PM

Dimitrov 7-5, 3-4 Goffin* (*next server) - Goffin breaks

Oh dear, a couple of Dimitrov double faults gift Goffin a 15-30 lead, and a forehand winner then takes the BElgian to two break points at 15-40. Stunning footwork once again from Goffin to run around his forehand there and swat away a winner. He repeats the trick on the next point, thundering away a 95mph inside in forehand to secure the break! 

Huge few minutes in the match here, and Goffin is now a couple of service holds away from levelling the match. 

7:40PM

Dimitrov* 7-5, 3-3 Goffin (*next server) - Goffin saves a break point and holds

Glimmer of a break here for Dimitrov, as Goffin sends a backhand long for 30-30. It's then a big chance for the Bulgarian, as Goffin nets a backhand for 30-40 and break point. A lengthy rally ensues, and Goffin saves it with a gutsy crosscourt backhand winner that just kisses the sideline as it flies through the court. Goffin then completes the hold a couple of points later with a swinging ace down the T. 

How big a moment could that saved break point end up being in this match? 

7:33PM

Dimitrov 7-5, 3-2 Goffin* (*next server)

Lovely ball striking from Dimitrov - especially a beauty of a forehand winner down the line - help the Bulgarian to a hold to 15. Big noise coming from the Dimitrov supporters now. 

7:30PM

Dimitrov* 7-5, 2-2 Goffin (*next server)

Second love hold in a row for Goffin, who has settled into a nice rhythm on his serve. 

7:26PM

Dimitrov 7-5, 2-1 Goffin* (*next server)

Dimitrov looks in control of the game up 40-15, but a missed backhand pass and a Goffin forehand return winner have us at deuce. It proves to be a temporary reprieve for Goffin though, as Dimitrov bangs down a service winner and an ace out wide to wrap up the hold. 

7:22PM

Dimitrov* 7-5, 1-1 Goffin (*next server)

Nicely done David Goffin. He arrests the slide with a first love hold of his own, helped on his way by a pair of aces to start the game. 

7:19PM

Dimitrov 7-5, 1-0 Goffin* (*next server)

Dimitrov looking to turn the screw early on this set, and he gets off to the perfect start by securing the first love hold for either player in the match. Goffin needs to steady himself. 

7:17PM

Dimitrov* 7-5 Goffin (*next server) - Game and first set Dimitrov

Big Bulgarian presence at the O2, and cheers of 'Grigor, Grigor' ring around the O2 as the players rise to their feet for the start of the game. The decibel level then cranks up a couple of notches, as some brilliant defence draws a Goffin forehand error for 0-30. It's then two set points for Dimitrov as Goffin sprays a forehand long to make it 15-40. Wonderful, controlled aggression from Dimitrov there. Goffin saves the first set point with a textbook big serve-forehand winner one-two punch, and he saves the second as well with a wrong-footing forehand winner up the line. Dimitrov was just a little too passive there. He gets a third set point though when Goffin sends a volley wide. Can Dimitrov take this one?  No, he can't. Goffin saves it with a service winner down the T. But the Belgian makes a mess of the next point and botches a volley to hand Dimitrov a fourth set point. Fourth time lucky for Dimitrov? Nope. He pushes a forehand long and we're back at deuce. Nervy tennis from both men, and it gets worse as Goffin forces a game point but then double faults at just the wrong moment. A dreadful forehand error from Goffin then hands Dimitrov a fifth set point. And this time he takes it, as Goffin nets a forehand. 

After 59 minutes, Dimitrov is a set away from the biggest title of his career. 

7:04PM

Dimitrov 6-5 Goffin* (*next server)

Ay ay ay, two double faults in a row from Dimitrov hand Goffin a 15-30 lead, and the Belgian really should win the next point as well but he snatches at a backhand volley for 30-30. An ace and a missed Goffin forehand follow to secure the hold for Dimitrov. 

Goffin will serve to stay in the set for a second time. This is the 23-shot rally I was talking about a couple of games ago...

7:01PM

Dimitrov* 5-5 Goffin (*next server) 

Goffin looks to be losing his footing in this first set after going down 0-15 here, but he steels himself to take the next three points with two good first serves and a backhand crosscourt winner. Dimitrov then nets a backhand return, and Goffin completes the hold to 15.  

Goffin has hit 12 winners to Dimitrov's four. The Belgian has been the player forcing the issue from the back of the court so far. 

6:57PM

Dimitrov 5-4 Goffin* (*next server) 

Big game coming up here, one that could well be decisive this set. The players exchange the first two points before the rally of the match ends on the 23rd shot with a brilliant Dimitrov stop volley for 30-15. Goffin produced some magnificent spins and angles that point, but it was Dimitrov who prevailed. Both players are at it again a couple of points later, and again it's Dimitrov who comes out on top - this time securing the point with a brilliant forehand pass on the run to make it 40-30. Goffin then sends a forehand long, and Dimitrov holds. 

Three games in a row for Dimitrov; Goffin will now serve to stay in the first set.  

6:52PM

Dimitrov* 4-4 Goffin (*next server) - Dimitrov breaks back

A couple of loose points from Goffin at the start of the game hand Dimitrov a 0-30 lead. Both players are on just 33 per cent second serve points won. Goffin then channels his inner Stefan Edberg and serves and volleys to excellent effect on the next two points for 30-30. But a double fault then gifts Dimitrov a break point at 30-40, and a missed Goffin forehand secures the break for the Bulgarian. 

We're back on serve. 

6:47PM

Dimitrov 3-4 Goffin* (*next server) 

That backhand from Goffin really is mesmerising to watch. He takes the ball so early, and uses it to devastating effect on the first point of this game to draw a missed Dimitrov backhand and move up 0-15. Dimitrov then bangs down his first ace of the match - a clean strike down the T - before easing to a hold to 15. Ok, so there will be some comfortable holds! 

6:44PM

Dimitrov* 2-4 Goffin (*next server) 

I would wager that we are going to have very few comfortable service holds this match. Goffin looks in charge at 30-0 before a missed forehand and a double fault has us at 30-30. A couple of big serves follow though, and the Belgian completes the hold. 

Good graphic below from the BBC of the six players, including Goffin, to have beaten Nadal and Federer at the same tournament. 

6:41PM

Dimitrov 2-3 Goffin* (*next server) 

Dimitrov chucks in a couple more loose errors but looks to be on course for a service hold at 40-30. Goffin saves the game point with another brilliant forehand return winner, before Dimitrov does eventually claim his first hold of the match when Goffin nets a forehand and then misses a service return. 

6:36PM

Dimitrov* 1-3 Goffin (*next server) 

A yelp of frustration from Goffin, as a passive point from him allows Dimitrov to get on top and thunder away a forehand winner up the line for 15-30. A nifty second serve from Goffin though outfoxes Dimitriov for 30-30, before a pair of aces secure the first service hold of the match. 

Goffin successfully consolidates the break this time. 

6:31PM

Dimitrov 1-2 Goffin* (*next server) - Goffin breaks! 

Beautiful ball-striking from Goffin helps him to 0-40 and three more break points. Solid serving from Dimitrov saves the first two, but Goffin takes the third with a stunning crosscourt backhand pass. 

That's three breaks of serve in the first three games, and Goffin has won as many games already as he did against Dimitrov on Wednesday. 

6:27PM

Dimitrov* 1-1 Goffin (*next server) - Dimitrov breaks back

The first cut to Becks leads Castle to say no more than "Davide Beckham". Anyway, enough mentions of Andrew Castle. 

Dimitrov forces a break back point at 30-40 when Goffin nets a forehand, but the Bulgarian sprays a forehand long of his own to waste the opportunity. Dimitrov earns a second one though, and takes it this time as Goffin sends a forehand long.  

Slightly nervy start from both men, and we're all square. 

6:22PM

Dimitrov 0-1 Goffin* (*next server) - Goffin breaks

David Beckham is in the crowd - Andrew Castle is going to absolutely wet himself when the cameras cut to him. "There's a man who knows a thing or two about bending the ball, and even he will have appreciated that Dimitrov passing shot. Lovely stuff.""

Away from the hypotheticals, Dimitrov makes a sluggish starts and pushes a forehand long to hand Goffin a break point at 30-40. Goffin though can't convert when he returns the favour with a long forehand of his own. No matter though, the Belgian earns a second break point moments later and this time he takes it with a brilliant off-forehand return winner crosscourt. Dream start for La Goff. 

Castle meanwhile is patronising the absolute crap out of Goffin in the early stages. 

6:16PM

Ready? Play

We're under way...Dimitrov serving first. 

Good stat below. 

6:09PM

Coin toss

Dimitrov wins it and elects to serve. 

6:07PM

Omen?

Lots has been made understandably of Dimitrov's 6-0, 6-2 demolition of Goffin on Wednesday, but the stats suggest it may not necessarily have too much of a bearing today. 

Tennis stats guru Luca Beck has crunched the numbers and shown that on nine out of the 17 occasions when two players have met in the Round Robin stage and then the final of the ATP World Tour Finals, the loser of the first match has won the second. 

That said, not many of those players will have lost the first match to quite such a humiliating extent...

6:06PM

The players are on court

Warm reception for both, and after a short warm up we'll be under way. 

5:30PM

Preamble

Afternoon all, 

So, this was unexpected. Today's World Tour Finals final feels a bit like turning up to a party only to discover that the only person you knew going has now bailed. 

The absentee from the O2 Arena this evening is of course Roger Federer, who was stunningly defeated in yesterday's semi-final by David Goffin. Legions of 'Fedfans' had bought tickets for today's final in anticipation of seeing their hero, so they may be a little disappointed to be watching the diminutive world No 8 instead. 

That said, Goffin should provide some very watchable tennis, and the sport is - or at least should be - about more than just the 'Big Four/Five'. Goffin for his part has already beaten Federer and Rafael Nadal this week - the first man to do so at the same tournament, by my calculations, since Novak Djokovic at this event two years ago - and conjures up delicious angles from the baseline, especially on the backhand side. 

That said, Goffin could be forgiven for taking to the court today with a degree of trepidation. Not only does his opponent Grigor Dimitrov lead the head to head between the two players 4-1, but he hammered Goffin 6-0, 6-2 just four days ago in the tournament's Round Robin stage. Goffin on that occasion looked like a man who hadn't slept for about a month, while Dimitrov played with the ease and confidence of a man lording it about on the practice court. 

Partly, though not entirely, because of Wednesday's mismatch, Dimitrov is the big favourite to win today and claim what would be the biggest title of his career. The Bulgarian has had his best year to date - an Australian Open semi-final and a maiden Masters title in Cincinnati among the highlights - and will finish the year as the world No 3 regardless of the result today. At last, Dimitrov, now 26, seems to be making good on the potential that saw him given the nickname of 'Baby Fed' in his youth.  

He is still prone to the odd lapse, including in yesterday's semi-final when he struggled to serve out the match against Jack Sock, but generally his temperament and shot selection has improved dramatically. Linking up with Andy Murray's former hitting partner Dani Vallverdu has been a massive factor in this regard. 

My prediction for what it's worth is a Dimitrov win in three sets, with Goffin rallying in the second to force a decider but ultimately falling short.
