What I don't get, is that he would bench Del Piero, just because players wouldn't reach the ball to his feet from what I understood from him..... like Iaquinta would be a better option and wise one.
Keeping one of our most dangerous players out and one of the few players including Pavel whom are able to change the game anytime, to leave him in such a match would be a crime.
Looking at stats, Ale's record at the olympico is pretty great if not amazing, doing Capello style and keeping him out in such a game would cost the team. So Ranieri wouldn't want that, or he'll regret like Capello... (Inter's freekick, Milans doublekick assist, Fiorentina and Roma's goals), Ranieri should probably ask Capello about them.
So, whoever thinks Ale should be benched, in a "fair play" i'd ask them to soap it
