We are five games into the new season, and while that is no amount of time to measure the success of a new signing at a club, it is still worth looking at who has made a good early impression. This is the point where a list is compiled and the all players mentioned go on to crash and burn, because that's how these things work, right? Anyway, here are seven summer signings made by Premier League clubs who have hit the ground running... Quite simply, Chelsea are fools. What a signing Nemanja...
Nemanja Matic - Manchester United
Quite simply, Chelsea are fools.
What a signing Nemanja Matic has been so far. The big Serb has performed impressively in every game he has featured in for his new club, and has elevated himself to an indispensable member of Jose Mourinho's starting XI.
Matic looks incredibly assured on the ball, and hardly ever gives the thing away. He has also shown fantastic defensive discipline, which has allowed the likes of Paul Pogba to flourish this season.
Eyebrows were raised at his price tag and age, but with every passing game Matic is looking like a bargain.
Romelu Lukaku - Manchester United
...Speak of the (Red) devil.
At the risk of opening up a can of worms, Romelu Lukaku has performed marginally better than Alvaro Morata in the red of Manchester United.
The £90m signing from Everton has flown out of the traps at Old Trafford and is gobbling up the kind of chances Zlatan Ibrahimovic missed last season.
He has made a solid impression at his new club - you know that's the case when its supporters make up a song for you, however inappropriate...
Alvaro Morata - Chelsea
Although it wasn't a Mesut Ozil-esque fan meltdown, some Real Madrid supporters were particularly unhappy to see their club sanction the sale of Alvaro Morata to Chelsea for £60m this summer.
The Spaniard missed a penalty in his first match against Arsenal in the Community Shield, but that has been the only blip for him so far, because he has made a seamless transition into Diego Costa's position as the main striker.
The elegant 24-year-old rises like a salmon when going for headers and has eased the worries of those fans who really wanted to see Romelu Lukaku return...
Mohamed Salah - Liverpool
Liverpool look to have flopped in the summer transfer window given the way things are looking at the moment, but one man they did sign was Mohamed Salah for a club record €42m - and it's already looking like great business.
The Egyptian had a blinding pre-season which immediately got Reds supporters excited, and he has made a strong start to life back in the Premier League following his poor stint with Chelsea a few years ago.
The former Roma man is electric, and suits Liverpool's play style perfectly and looks to be this year's version of Sadio Mane.
Pascal Gross - Brighton
Brighton's £3m summer signing from Ingolstadt was a snip, and some of his performances so far have had Seagulls supporters scratching their heads as to how they managed to get him so cheap.
Revealed as the Bundesliga's top creator last season, he has very much picked up where he left off and is the source of everything that's been good about Brighton so far - his two goals against West Brom, on top his two assists and fantastic work rate, show that there are multiple dimensions to his game.
Sead Kolasinac - Arsenal
Another left-back to make a huge impression in the Premier League after five games is Arsenal's Sead Kolasinac.
The Bosnian was signed for absolutely nothing in the summer after running down his contract with Schalke and looks like he was born to play in the English top flight.
Strong, fast and aggressive in the tackle, Kolasinac has staked an early claim as the division most physical player, and the Arsenal fans absolute love him for it.
Benjamin Mendy - Manchester City
Not only has Mendy made an impression on the pitch with some attack-minded displays at left wing-back, but the Frenchman is an absolute treat on Twitter. If you're not already following him, then minimise this article and allow yourself to be absorbed into Benjamin's world of banter.
Jokes aside though the former Monaco star looks like he's going to be a fantastic signing for City, and is a monumental upgrade on Gael Clichy and Aleks Kolarov.
