The Italian goalkeeper was strongly linked with a move away from Turin this summer.
Reports in Italy claim Buffon could leave the Italian outfit after the World Cup and move to the Premier League, with City and the Gunners believed to be interested in his services.
But Buffon's agent Silvano Martina said today: "I don't know what else to say with regards to Buffon as it seems that he is the only Juventus player who should leave.
"Considering the ongoing reports, I want to remind everyone that Buffon is under contract with Juve and that next season he will play at Juve.
"When he was asked hypothetically where he would want to play if he left Juve, he always said his first choice would be England, but there is nothing else.
"He never said he would leave.
"(Luigi) Del Neri is an intelligent coach and knows he can count on Buffon."
Del Neri is expected to be unveiled as the new Juventus manager later this week and already stated his wish to have Buffon in the team next season.
The 32-year-old Buffon is under contract with Juve until June 2013.
