The veteran attacker netted once in Juve's important victory after previously finding the net in the Bianconeri's Coppa Italia semi-final against AC Milan in midweek, and Conte understandably feels Del Piero is currently a key player for the Turin giants.
"Del Piero? He’s in excellent form at the moment, and he was absolutely decisive in these last two important matches. His experience and character are fundamental in this crucial stage of the season," Conte was quoted as saying on the club's official website.
The Juventus trainer then went on to reflect on the win over Inter, and had words of encouragement for the Giuseppe Meazza side.
"We faced a great team, and it’s really hard to understand their current position in the table.
"In the first half, they caused us some difficulties. During the break I told my lads that we would revert to a three-man defence. I don’t know whether this change was decisive, but it helped turning the game around."
Juventus remain second in the Serie A table, whereas Inter have dropped to eighth spot following this weekend's results.
