The Old Lady are now five points behind Inter following their 2-1 win last night.
“It was wonderful both in terms of result and the performance, this game had a special sensation for us,” smiled the captain.
“We wanted to give ourselves a signal about our capabilities, our potential and what we can do this season.
“That arrived and with it came the result, so we are extra happy.”
Juventus face Bayern Munich in a crucial Champions League tie on Tuesday and need at least a point against the Germans.
“This can be very useful going into the Bayern game if we are smart, humble, focused and realise we can play with this aggression against everyone,” added Del Piero.
“If we forget that, then we run the same old risks.”
