I find it very strange that people are worried about this game or worried that we're playing 3-5-2. We played that in the Coppa game with half a squad and they were almost full strength. Yes it was the Coppa but still we have the edge over them this season.
We should trust Conte. He's proved that he know how to beat them, he works daily with these players and knows them better than anyone else. If he thinks 3-5-2 is the best option then so be it.
I honestly don't think the formation matters a great deal in this game, each player will have a role to play and if they're good enough they'll execute the plans properly and we'll win. Big games like this are all mental battles. Looking at the comments from their team this week, we hold the advantage already.
