The Bianconeri goalkeeper believes he has just a few years left at the top level, and stressed how much energy is being drained from the players by their European clashes.
The Italy international has been at the Turin-based club since 2001, when he joined from Parma, and he was key to the team's Serie A success last season.
Buffon believes that he has a few years left at the Juventus Stadium at the very least, but wants to avoid becoming just an average shot stopper by resting on his laurels.
"I’m convinced I can remain at a high level for another two or three years and I’d be better suited on a short contract, but I'll talk with them," the 34-year-old told Mediaset Premium. "I’ve had a huge career and do not want to lie down on a long deal, I want to feel more on my toes, otherwise I’d become just a ‘normal’ goalkeeper."
Juve beat Palermo 1-0 on Sunday and Buffon has revealed that part of the reason behind the club's lack of a resounding victory could be the effort being put into Champions League progress, having topped its group with a 1-0 away win against Shakhtar Donetsk on Wednesday night.
"The European commitment there is taking a lot of energy, especially mentally," the Italian admitted. "It’s not easy to make a commitment during the week and then [on] the Sunday have the same stimulation to perform."
