"I have been training for the last four weeks and though I have played just one practice match it will be okay tomorrow," the 39-year-old Del Piero told reporters on the eve of the match.
He added:"I can assure you I will fight till the end for my team."
Both were part of the Juventus team when the Serie A giants were relegated to second division following the 2006 match-fixing scandal that rocked Italian football. They were also the ones singing the redemption song when the club, also called the Old Lady of Turin, returned to top-flight football and dominated the league.
"It will be fun to play against him (Trezeguet). We have played for so long together in Juventus and we were one of the best strike partners. Now, we will be playing face to face," said Del Piero when asked about playing against the Frenchman who, like the Italian, is also a World Cup winner.
"For the last five to six weeks, my team has trained rigorously. As this is an entirely new tournament, we have hardly any idea about the strategy of the opponent team, but they also have no idea about us. The practice matches have been good and we have build our co-ordination well.
