Buffon has been linked with Manchester City and Manchester United in recent weeks.
“I think you will have seen things on TV and in the newspapers over the last few days and now I want to make it official – I am not leaving Turin next year and will remain Juventus’ goalkeeper,” a statement on Buffon’s website reads.
“I have had two discussions with John Elkann and Jean-Claude Blanc to clarify things and they both gave me positive responses about the future of the team.
“My fear wasn’t that we wouldn’t win next year but that maybe it would take three or four seasons.
“Everyone at Juve wants to create a positive group that can compete for everything and I am a lot calmer now.
“All that remains to do now is to finish the season as positively as possible. We looked a lot better against Milan compared to the previous games and it felt like we were back to our level.
“We need to confirm the improvement in the final three games, starting with Sunday’s test against Atalanta.”
