Don't get me wrong, Nick. I think Milan is still a quality club capable of challenging the best of them for the title. You don't win 8 in a row for nothing.
But IMO, Carlo is more in the vein of the traditional coach (the most common kind) that adds little value to the team. I think Milan is capable of doing at least as well without him -- and that includes the year they won the CL. And Milan is a club that, IMO, deserves better. When I have to pick someone to fault for their failure to take lesser clubs seriously enough, to have the team mentally prepared, the coach is the first (though not only) one I have to blame.
