“It's not an issue of shaking off the 4-2-3-1. We had a more attacking set of players than against Barcelona. We've got some coming back from injury and soon will have everyone reaching full fitness," Allegri told Mediaset Premium.
“We kept Douglas Costa wide with Alex Sandro also too wide, so we were unbalanced. I adjusted things to bring Douglas Costa back, so we found Mandzukic and Dybala between the lines.
“In order to go all the way, we need everyone. Claudio Marchisio was missed and now it's important to have him back.
“Last season we had some players who performed a certain way and aren't playing on the same level now. My job is to get the best out of the players I have at my disposal. There are some who aren't in their best physical and psychological shape, so it's only right those in the best condition should play."
