Criticise, but there is nothing more you can do with it. If letting Trezeguet go was so bad, why didn't Del Piero himself say anything? Because he knows it was best for the club and for Trezeguet. Trezegoal has got his career back on track now.
Statistics have nothing to do with the case, look at Amauri statitstics from 2008 and say that he'll get back on track. There is no guarantee that Trezeguet had copied his previous statistics. The statistics are just your dumb argument, they have nothing to say anymore. That was past.
