Gianluigi Buffon has told Juventus they must build a side capable of challenging for honours if he is to remain in Turin next season.
The most expensive goalkeeper in history stayed with the Bianconeri following their enforced demotion over the summer despite attracting interest from a number of top sides.
After deciding to stay Buffon has played an important role in helping the Old Lady to shine in Serie B so far this season, and, with his stock as high as ever, has again been linked with a potential exit.
Chelsea and Milan are both reportedly pondering a move for Buffon in the winter transfer window, but the Italian international has already pledged to stay at least until the end of the campaign.
With Juventus just one point behind Serie B leaders Napoli even taking into account a nine-point deduction resulting from a match-fixing punishment, it looks likely that Didier Deschamps' side will regain their top-flight status this term.
However Buffon has warned the Italian outfit that they must convince him of the club's ability to be competitive if he is to stay a Bianconeri player into next season.
"Because the probability I'll remain at Juventus will grow it is necessary that around me and around the others who will remain, there will be a really competitive side," Buffon told Sky Italia.
"This surely would be the first incentive, but at the moment we don't know what will happen."
Buffon also shrugged off his likely defeat in the Ballon d'Or race, with former Juve team-mate Fabio Cannavaro set to be announced as European Football of the Year on Monday night.
"It's not a big sorrow," Buffon continued.
"Should I win it in the future it will mean that the whole team would have helped me and that together we would have got important aims."
