From all the news we have seen so far, it can be assumed that Guardiola is not interested in extending his contract with Manchester City. This is probably going to be Guardiola's last season with Manchester City. Guardiola is now interested in becoming a national team coach. But we do not know if this team is Brazil yet. I have not seen any rumors about this. However, City is in very bad form now. They have lost four matches in a row. However, I am waiting to see if Manchester City's performance improves after the international break. City's squad is strong, Guardiola is also a very experienced coach. So it is hoped that City's performance will stabilize in the coming matches.
Pep Guardiola has really made his name at Manchester city and not only at Manchester city but to other top European teams like Barcelona and Bayern munich so it has been a successful coaching career for him, if he decides to switch over to coaching any National teams, he may have the opportunity of winning the world cup. Whether Manchester city performs better or not, i think Pep can decide to leave the team to coach any top clubs that may need his service but due to how successful he has been while coaching club sides, making a move to National team will be more preferrable than coaching another club side again. Even if the speculation of a possible move to the Brazil National team is a rumor, i believe it will be clear on his final decision soon so let us just watch out for his next action.
Manchester city might make improvements after the international break but i don't think they can be able to maintain consistency till the season ends.
If Guadiola is able to win trophies for Manchester City this season, I believe he will want to leave and coach in an international league, because he has already coached many top European leagues and won many titles in any club, so he has already done everything in Europe, winning the league, Champions League, and small cups in all competitions. Now he is already weak, and he can't perform as well as he used to in the Premier League, which he has won back-to-back. so am sure they won't achieve the league trophies this season. Liverpool are the favorites this time, because they are the one that are still doing well in the competition currently topping the league and even the ucl.
You are correct. if Guadiola didn't renew is contract with Manchester City, he can move to Brazil national team. he will be a nice move, because he will be very difficult if not Guadiola will win the world Cup for them 2026. because he as the experience and a coach and he will no what do and achieve the trophy. In my opinion, he will be difficult for Guadiola to coach this season because Manchester City will still want him to renew his contract because he has won many things for them, and before getting a coach like Guadiola, it will be very difficult. Anyone knows that Guadiola is the best coach in premier league, but now I don't think he will be the best this season dew to several injuries players in the team.
