on current form, he doesnt deserve to start. Cassano and Miccoli would be better in my opinion. However, if he regains his form as he did before the world cup, then i say go for him as a starter. Cassano and Miccoli are both great young talents but none have experienced a major tournament.
Del Piero's best chance to prove himself was last world cup and i believe that with the short amount of time he had on the field, he played very well and proved that Traps is a senile man.
one last point. When Del Piero enters the pitch off the bench, he seems to look more determined and he generally plays better.
i suppose its going to be down to what formation and who traps' chooses in his squad.
but on current form, del piero doesnt deserve to be starting IMO.
