Not as good as Storari imo, but he is a lot younger and Italian keepers often reach a high level past their thirties. He'll probably be sold in January anyway because of his situation at Cagliari and the fact Agazzi has done well, so I don't think we'll be looking at him.
De Gea looks like he is going to be a great, our problem is that Buffon still has years left fitness permitting, so by then De Gea could be established at a very big team. But then Real Madrid, Barcelona and Chelsea are in the same boat because they have strong keepers. Hopefully he doesn't go to Man Utd.
