I dont think his tank is empty, Adriano. Most Milan fans I know thought of him being fundamental to their squad in the last couple of years and see his departure as a big loss.
At least with Ziegler and Lichty he'll have some attacking flank outlets. Now just put him in there with two solid CM's and we should have a midfield that at least plays smart football and doesn't force shit, like we have for the past six years.
