"I'm absolutely aware of the great effort Juventus Football Club has made to bring me here," he told the club's official website. "I feel the responsibility of wearing this number and I am aware of the great responsibility of representing Juventus and playing for the club so this number is certainly a great challenge.
"Top players have worn it before and I was number 10 with Boca Juniors before, and Diego Maradona played in it too, so the great responsibility is now that I'm going to play in this great club so certainly the greatest challenge is to do my best.
"Obviously I didn't want to forget Del Piero who was the last player to wear number 10. He is a person and player that I greatly respect and who certainly represents an emblem and symbol of esteem."
Tevez played for City for four years, scoring 58 league goals in the process.
