Humble and intelligent Del Piero???? Bwhahahaha, that's the funniest thing I've heard since Darko Pancev moved to Inter. Del Piero is as intelligent as Rivaldo's right foot. And humble?? The man thinks he's bloody God, too bad he is really just Godot!
Totti is arguably even dumber, granted, but at least he won't try to appear intelligent, and he seems to have a sense of self-derision as he just published a book quoting all his famous linguistic blunders (it became a best-seller in Italy, lol). And he's not arrogant, he's just roman (alright the difference is minimal).
As for consistency, the comparison is flawed : Totti is a true and indispensable leader for Roma, and he can single-handedly lead them to victory, whereas Juve can easily do without Godot, as you all must have noted during his last prolonged absence from the game.
This is even more evident with the National team : when Totti is absent, the lights go off. Take Del Piero out and you can always replace him with Cassano or Miccoli.
