"I think that Ranieri has a way of seeing things that only he can truly explain," Del Piero said at the final whistle.
"I am happy to have scored two goals on Ciro Ferrara's debut, but don't forget I had netted 19 with Ranieri.
"Unfortunately they've been lacking recently and I'm sorry we arrived at this stage. Ferrara gave me confidence and kept that up throughout the game."
Del Piero did have some words of comfort for the Coach who was fired on Monday, though.
"One has to admit that in times of victory we were all great, but during the difficult moments it's not as if Ranieri was entirely to blame.
"Those who are called upon to play, like me today, have to give their all. The same happened with Pavel [Nedved] and Mauro [Camoranesi]."
