The Old Lady directors considered retiring the iconic jersey, but the Italian forward asked the club to keep it available, an opinion shared by the former Milan man
It remains unclear where il Pinturicchio will play next season, but it is almost certain that the veteran will leave the Old Lady after 19 years of service.
However, Pirlo revealed that the 37-year-old does not want to see his number withdrawn from service.
"Juventus wanted to retire the number 10 shirt now that Alessandro is leaving the club, but he asked them not to do so," Pirlo revealed in an interview to Sky Sport Italia.
"I agree with his decision. It's unthinkable that someone will be up to Del Piero's legacy soon, but I am sure someone will, in the future."
The Italian midfielder believes many players dream of wearing the number 10 jersey for Juventus, and that is "a very beautiful thing", but he denied that he will take on the responsibility next season.
"I am staying with 21", he stated, "I've always had it and I want to keep it."
