Juventus claimed the 0-0 draw they needed against Barcelona to secure their place in the Champions League semi-finals. Wednesday's second-leg wasn't quite the spectacle some were hoping for, as the Spanish outfit failed to come close to overturning the 3-0 aggregate deficit. Whilst they will be left to reflect on a disappointing European campaign, the Bianconeri's dream will continue as they edge ever nearer to glory. Here are five things we learned from the quarter-final second leg meeting...
As poor as Barcelona were at times during the two legs, Juventus were masterful. Whilst they showed a great attacking threat in Turin last week, the performance at the Camp Nou was an absolute masterclass in defending.
Well organised, strong in their tackles and rarely out of position, the Bianconeri's defensive showing was textbook 'Italian' and explains why they have not conceded a goal in over 500 minutes of Champions League football.
For some, the Old Lady's resilient display may have been a little boring, but for anyone who appreciates the art of defending then they would surely agree that the Serie A leaders were a joy to watch.
If there is a blueprint of how to stop Barcelona from scoring then Juventus provided it.
Compact and narrow, the Old Lady provided very little room in the middle of the pitch and only allowed their opponents time and space out wide.
Luis Suarez was quiet, Lionel Messi wayward and Neymar was often left to battle through a crowd of defenders on his own.
The Catalans had no answer to the visitors' stubborn resistance and look in desperate need of remodelling, as their once imperious system established under the outgoing Enrique now looks like it has run its course.
For all the talk about Paulo Dybala, Gonzalo Higuain and Gianluigi Buffon, there remains a number of unsung heroes in this efficient Juventus side who deserve special praise for their efforts.
Miralem Pjanic is not a household name, but the Bosnian was everywhere on Wednesday evening and probably spent half-time in the Barcelona dressing room such was his desire to keep a close eye on the opposition.
Wherever Pjanic wasn't, one of Juve's centre backs was, as both Leonardo Bonucci and Giorgio Chiellini shut down the Blaugrana's attacks time and time again.
They may not be the most attractive players in Allegri's XI, but make no mistake, all three are just as valuable to the team cause, even if some of their teammates regularly take the plaudits instead.
On paper, the Barcelona starting XI on Wednesday looked just as strong as those that have previously won honours at the club.
Yes there was the raw talent of Samuel Umtiti and Sergio Roberto, but there remains a core group of players that have so often come up trumps for the Blaugrana.
And yet despite being close to full-strength, Barcelona looked a shadow of the side we think of from seasons gone-by. The uncertainty over the manager's role won't be helping matters, but it may be time for some of this team's wonderful stars to take a back seat.
Fresh ideas, not to mention players, are badly needed at the Camp Nou. The comeback against PSG masked the frailties in this Barca side and though many were not fooled by last month's heroics, we have all been reminded once again that it is well and truly the end of an era at Catalunya's most famous football club.
As one team approaches the end, another steps forward and with Juventus now appearing to be at their peak, this could well be the year that sees them claim the coveted Champions League trophy.
Whilst those in England admirer Tottenham's all-round capabilities, the Bianconeri have shown their team is on another level when it comes to having the complete package.
A deadly mix of top class strikers and some of the game's best defenders means that Allegri's men are serious contenders to win the competition.
They will be quietly confident of securing European glory and with a defence that has been breached just twice in 10 matches this season, anyone paired with the Old Lady in the last-four will surely be worried at just how they are going to find a way to beat the Italian champions.
