Milan have signed Massimiliano Allegri. After 11 years, Allegri will coach Milan again. He won a championship back then. Then he had a very successful period at Juventus. Now he's going back to Milan. I think it could be a salvation for Milan, which has been bad lately. Milan will not play in the European cups next season. By focusing only on Serie A, maybe they will be more successful. It's also important how much budget they will allocate for transfers. Allegri will want new players but the budget may be more limited.
I admit Milan needs a title, Milan needs UCL, but for next season I will not expect too much even with Allegri. Milan also needs someone who is able to see the talent of players to be targeted. Milan is unlikely to spend a lot of money on player transfers, this has become a tradition for AC Milan. Allegri must think hard to maximize the transfer market to get players who fit his criteria. Sounds hard for him to rebuild this medicre club.
