He did well.
He inherited a team that just came back from Serie B and he managed to do a remarkable first season.
When, however, the team should have been brought to a superiour level (from January 2009 on), he failed to find the second gear.
The only serious issue I had with him are his stuborness of overplaying Nedved at the expense of Giovinco. I know it's not easy to find a place for Giovinco when both Nedved and Del Piero are on the pitch, but I firmly believe that a top coach would have found a system permitting to use the best of these three players, including by rotation.
He did a correct and competent job, but failed to step up to the higher class. That said, he always respected the club and I command him for that. He has endured some rough times recently.
Good luck on your next jobs, Claudio!
