Del Piero: Juventus have badly underperformed this season
Del Piero felt the result was the "epitome" of their season.
"This draw is the epitome of our season. We are a team that can do better and produces less than what it can do. Surely we are missing something, if we knew what we'd already have solved the situation," said Del Piero.
"Now we just have to work even harder to do better in the last two games and especially next season."
