Although he has already established himself as an icon throughout his 23-year career, he wants to go out on a high.
"This could be the last year and I would like to be a protagonist, as I have always dreamed of being," he told reporters. "A year in which we see the Buffon that pays attention to detail and is eager to make his mark. To do that, I have to be important. I will work for this next year.
"The team goals are a consequence of what you have given and taken throughout the year."
Juventus are said to be close to signing Szczesny from Arsenal, while Donnarumma is pushing for the No.1 spot in the Italy national team, and Buffon welcomes the competition to keep him at the top of his game.
"I've always been a rational person and I've always looked for the meaning of things. It's right that Juve want Szczesny and that there is a good player like Donnarumma at the national team.
"For me it will be a great motivation twice because, although I am 39-40 years, I have to maintain my place. If I no longer want to play, I'll stay at home because Donnarumma and Szczesny are good goalkeepers by merit, not because someone gave them something."
