Well that wasn't a terribly interesting match from a tactical viewpoint.
Obviously there was plenty of incident and excitement, but not all that much worthy of analysis.
Both teams were focused on having a huge presence in midfield and both teams struggled to get past the opposition midfield. Both defences struggled to contain the opposition attack when they were left exposed by the midfields.
Was interesting seeing Allegri adapt the 3-5-2 to play Roma's fairly unique front three. First half saw Juve really twist towards a back four, with Caceres marking Gervinho. In the second half Lichtsteiner went a bit deeper and Juve pushed Bonucci up to close down Totti. Not using a midfield to pick up Totti meant Juve had more chance of winning the midfield battle and even gave them enough security in there to feel able to try and get Pogba out of midfield and into space to try and influence the game.
Was a good sub by Allegri to bring Morata on because, aside from Llorente not playing well, the game developed in a way that suited Morata more than Llorente. Roma tried to push higher up in the second half and impose themselves on the game. That meant there was space in behind/down the side of them for a mobile forward to run into the channels.
Was also notable how wide Pogba played for long periods of the game. That helped to block Maicon and also got Pogba out of the midfield crowd and got him some time on the ball - not that he made much of that time. It sucked Roma over to that side of the pitch and meant there were chances when Juve switched the ball quickly, but they didn't manage to do that very often.
Anyway, it's two very good teams and it is was a pretty even game. Despite the result, Roma should take a lot from it - considering the number of players they were missing - in terms of confidence in their ability to compete with Juve.
