Poor performance for the most part.
Giving the ball away cheaply, build-up play that is too predictable and playing in a way that made it really hard to put any pressure on Milan when they had possession.
I hate 3-5-2 against 4-3-3 because one of two things almost invariably happens: you either play 3 v 3 at the back and leave yourself very exposed or you play 5 v 3 and end up getting pinned back because you don't have the players high enough up the pitch to win or keep the ball.
Tonight it was the latter.
Juve, particularly in the second half, were playing 5 v 3, so Milan had heaps of comfortable possession and Juve never really looked capable of hurting Milan. That's an okay thing to do when you are winning, but at 1-1 Juve really ought to have been trying to take control of things.
At least Conte changed to a back four for extra-time. Pattern of the game didn't change much, but getting Giaccherini higher up the pitch at least helped Juve pose some sort of attacking threat during that period.
Bonucci had a very good game.
Caceres was decent enough and Vucinic made a difference when he came on.
Would be pretty hard pushed to say anything very complimentary about the others.
