There are only a few players who are really worthy of playing for a club like Milan, they are: Mexes, Abate, De Sciglio, De Jong, Montolivo, Balotelli and maybe Poli (I need more time to evaluate him).
The likes of Muntari Constant and Zaccardo need to be shipped out ASAP, they are a problem in fact because they are way below the quality level of the rest of the team and so they form a weak point on our left side. Zaccardo is just a bad player who wasn't even good enough in 2006 when he was called up to the Azzuri squad.
Then you have the likes of Zapata, Matri and Birsa, players who do possess some sort of quality but are not the type that should be starting games. Matri I would have preferred not to sign him to begin with due to his age but since he is here I can see him as a good 12th man who might give us options off the bench and change our approach to the game. Birsa needs to build up some strength but he possess football intelligence, Poli is a good player but he does seem to overcomplicate things at times.
Then you have the likes of Robinho and Kaka, players who can be world class but I just don't see them being game changers anymore.
There seems to be a shortage of good CBs on the market that we can afford, someone with the intensity of Benatia would have been ideal, maybe Daniel Agger can be an option but he is frequently injured, I wonder what happened to links with Papadopoulos from Schalke. We also need some better option in attack to help out Balotelli and distract defenders from his presence so someone who can finish half chances is needed, either a box poacher or a player who runs on to through balls. In midfield a player like Andre Ayew I think would be good because he covers so much ground and would allow our full backs to join attacks us he shoots from distance and can be used as an AM
