But he won't. As long as he's here he'll require playing time. Not as a starter always, but he'll want to start at least 50% of the matches.
If we have Cassano, who is now a better player than Del Piero and will be in the future too, there will be absolutely no place for Del Piero. He can get only those matches when Cassano will be rested, or some meaningless coppa matches.
Del Piero won't accept that, many fans won't accept it and frankly, the board will not accept such situation neither. Del Piero will not keep quiet, Cassano is crazy, you have problems in the team.
Plus, i'm not too sure if Cassano can work in the same team with Diego.
Both of them are the center of everything in their respective teams and i don't know how well will they play if they don't get a free role. Both of them can not get a free role though.
Then again, Cassano-Totti used to work fine, so i might be wrong.
