I don't believe Guardiola would want to change teams. Everything is fine with the Manchester City team at the moment. He is the boss of this team. The players respect him a lot. I'm sure we'll see a few more great seasons. If he goes to another team one day, it could be Barcelona.
I also still really want to see Pep Guardiola train Manchester City and still haven't thought about which team he will go to in the future, because Manchester City is now more suitable for how to train Pep Guardiola so that the team will definitely continue to work with Pep Guardiola in the long term as long as the team can continue to be at a better level in the seasons to come.
Personally I think a good coach or manager like Guordiola should change club for another new challenge to prove his worth as one of the best manager in the world having achieved his aim and objectives at Man City, Barcelona, Bayern Munich though couldn't win UCL with Bayern Munich but with Man City he had won every trophies except the World club cup which I believe he will win in December, there are equally good club in Europe where he can prove his mettle to win UCL trophy, club like PSG is a perfect choice for him because they have the financial resources and capacity with quality players in their yet they couldn't win UCL trophy,
in the end everyone admits that Guardiola is one of the best players after successfully bringing Man City to the treble title but in the past some people doubted Guardiola talent when he couldn't give anything at Man City.
now let just take positive thoughts about Guardiola that in reality he is a great coach with so much experience but even so he has a bad thing that I really don't like, namely when he has achieved what he want, for example the champions league title after that he will leave his team. well, this is what I didn't like about Guardiola from the past and it might happen for Man City.
we can only hope that Guardiola doesn't actually leave City until the season is over.
