He does it all the time, trying to win us soft free kicks. And we can't blame him. He knows that there is almost no other way this team to create chances and break defenses so he's trying to win us set pieces through his reputation.
Unfortunately this year refs in Italy were instructed not to interfere with the game too much and call the softer fouls, so most of the time Del Piero ends up on the ground without winning a free kick.
