We have 3 matches before Atletico Madrid. I would prefer to use all 3 matches to experiment and find some midfield combinations that work better. I fear that Allegri will feel like his back is against the wall and he will play the status quo, happy to take 3 points against these small teams.
I don't think it will help us prepare for Atletico though. We know what the usual suspects in midfield can produce. Why does the CM beside Ronaldo always have to be Matuidi? What are you risking by trying someone else there? Will we lose to Parma if you try Pjanic higher up the field? If you try Bernardeschi at LCM, beside Ronaldo, and Matuidi on the right?
