When it comes to Pep Guardiola I don't expect him to manage another Premier League team ever after leaving Manchester City in the future. Because we have matched him with Manchester City so much that I can't think of him as a manager for another English team. Maybe he would return to one of his old teams later on who knows.
Those teams are Barcelona and Bayern Munich though. Both of them must be contented with their current managers but Guardiola is also not going anywhere now in the end. Maybe in the future this might really happen.
Pep Guardiola may have made the decision to leave Manchester City for reasons that perhaps cannot be explained to the public, so Pep Guardiola prefers to look for other reasons so as not to make Manchester City's condition worse. It is possible that Pep Guardiola will return to Chelsea and improve the condition of this team to get into the top ten again from the top of the standings.
Although Pep Guardiola won three trophies last season namely the most awaited one which is Champions League title, yet he doesn't want to leave the club since his contract is still running. I think he will continue with Manchester City as much as possible then he might train a National team or a top team in another league like Bayern Munich or PSG or Real Madrid maybe.
It is hard to know his next decision, just like Klopp, until their contracts come to an end. The number of accurate rumours about coaches are way less than players one.
