There will be a lot of links about Pep Guardiola but obviously we know that Pep has extended his contract with Man City, meaning that nothing else has changed, it is certain that the news involving Pep to Brazil is excessive, even for next season it might be different news.
So far Pep is still comfortable coaching the club so he extended his contract with his current team, has made many contributions including several trophies so he will not just leave.
But I believe in surprises where he can decide to leave, like Klopp leaving Liverpool suddenly.
I am sure, Manchester City will always try to extend Pep Guardiola's contract, because basically Manchester City is also very lucky to have Pep Guardiola in the Manchester City coaching chair who has succeeded in making Manchester City get many trophies. Thus, the only reason Pep Guardiola leaves in the future is, Pep Guardiola himself decides to retire or maybe chooses to leave and look for a new challenge by coaching the national team, maybe. But, the point is, Manchester City will NEVER not offer a contract extension to Pep Guardiola, because of course Manchester City will always extend Pep Guardiola's contract, and that is good for Manchester City as long as Pep Guardiola accepts the contract extension.
I don't see any reason for Pep Gaurdiola to retire from coaching as far as the media is concerned, but he was interested in national teams like England but the offer never happened because Pep Guardiola still wanted to be at the club.
Man City will definitely keep Pep Guardiola until he continues to do his best, meaning where he can continue to provide trophies, if for example Man City starts to decline I think the club management will consider again to extend his contract.
