First of all, I think no one questions the talent of Del Piero.
The question is that:
Is he still capable to show his geniality on the pitch?
A guestion impossible to ask imo. The reason is simple. Del Piero's as a player can be defined by one word: unpredictable .
His decisions, his dribbling, his positioning and passing are all unpredictable. He is the very rare kind of player, who finds the 3rd (and usually the best) soliution in a situation which seems to has only two. How many times it happened? Most of the crowd thought it's not DP's game, he is just suffering on the pitch gave up fighting the rough defenders, seemingly unmotivated, tired, waiting to be substituted, and a second later, when he receives the ball he performes pure magic.
He dont need to be given the next season to prove. He deserves it on his own right.
Miccoli can play better than Dp when Alex is out of form, but no chance for him do that when Alessandro Del Pierro plays as he can, as only he (not even Totti) can in the serie-a.
