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.
Pep could leave City if they successfully defend the League trophy, but it is too premature to say that City will not win any trophies this season, after all they still have a chance to win trophies and defend their title in the Premier League. City is only 5 points behind the team at the top of the standings, moreover the Premier League still has many matches until the end of this season. It is true that currently City can be said to have experienced a decline in several of its matches, but there are many factors that are the cause, one of which is that several of their players are injured. We may assume that Pep this time needs time for his team to recover its performance, or he will not win any titles this season with his team. That could happen, and is still within something reasonable after they have always been consistent in the last few seasons. However, it is possible that Manchester City will be able to return to its performance and defend the League trophy again.
I also read some rumors that Pep was linked to the Brazilian national team, but I doubt it a little. and it is true that Man City has compromised on a new deal with Pep Guardiola, although it will only be valid for one season with an option to extend for another season. with this new contract, all rumors that reported Pep would coach one of the national team squads have been dismissed with his new contract with City. reportedly, there are several factors that make Pep still stay at Etihad, one of which is his family and the players. reportedly, City's players still respond well to Pep Guardiola. regarding City's ability to defend the title or not, let's let time decide.
