You are missing the point entirely. Del Piero was treated worse than Totti and he deserved to play more not because he was a club legend, but because he was way better than Borriello, Matri and Quagliarella. The club publicly forced him out and humiliated him by saying he can't stay regardless of the salary, but Buffon can stay as long as he wants. Yet, Del Piero kept quiet and helped the team win the Scudetto. Totti can barely walk, he has no place in this Roma team and should have been kicked out 2-3 years ago. In fact, Roma have treated him extremely well. And now that the team is winning without him, he goes out bitching.
The point is - Totti is a piece of shit.
