Milan have lost all in one year:
Zambrotta, Nesta, Silva, Seedorf, Gattusso, Van Bommel, Inzaghi and Ibra.
Nesta, Silva, Van Bommel and Ibra were starters. They played very important roles in their respective positions.
The Nesta - Silva partnership was great for them, losing those two is a huge blow to them...no matter who they replace them with.
Van Bommel played as an anchor for them...who hasn't been properly replaced yet nor do they have another capable player doing what he did.
And Ibra is Ibra. No need to say more.
On top of all that, they're fullback situation is piss poor as well. Abate is decent, but their LB side is a disaster.
Milan have huge, gapping holes that need filling. I don't think they have the resources to do so. Not even with that 70M.
