Yes, and if you look at the overall result, then I would say that Guardiola had a very average one - this victory was hard-earned (I don’t mean today’s game, but a long way to this victory after so many failures every year). I don't think that Guardiola will leave City - the club has complete dominance in the Premier League, and Guardiola is not one of those who like new challenges. There is no more convenient club than City now for Guardiola.
I am not sure whether Guardiola will remain with Manchester City or not but honestly the club is one of the best one in Europe and it is hard to find a better one.
If he would like to achieve another thing then there is PSG that's dreaming about Champions League title and they have enough money to spend for building a team. It is up to him to decide after all. Meanwhile congratulations to Manchester City this victory!
City have endless money to take the best from the market (Haaland, KDB, etc.) or close to the best for an endless search of options (as was the case with the defenders). It would be strange if this project did not produce results. It's as simple and boring as 2x2=4, which is why normal leagues (the near-ideal sports leagues in the US) have salary caps, budget limits, and so on. which do not allow one club to dominate indefinitely simply at the expense of finances.
