Seeing teams not willing to sell players and Marotta asking around so fast means we didn't see this coming so he wasn't put on sale but he asked to leave...
While I expected that we might sell vidal , I am surprised at his choice of going to bayern unless that is the only team searching for him which I doubt . Imho guardiola won't know how to use him .
As i mentioned more an AM, he has started more games as an AM than CM for us last season.
Secondly, his role is his tactical flexibility from the bench like Pepe. If Allegri needs a wide men, or an AM Pereyra can fill in from the bench.
