He asked to leave. Hands were tied. Perfectly acceptable excuse.
Benatia acts everywhere the same.Firstly was crying at Roma,then Bayern,now us.I don't give a fuck that he leaves.Wasn't bad centre back but not somebody to feel bad about his departure.Also an injury prone player.
Perhaps Allegri feels that Atalanta are a bigger threat so decided to rather play him in the Coppa against them. There will be quite a lot of rotation between the three I feel.
