100% true. Many praise Guardiola, but forget that he had the Barcelona of the golden generation of Spain, then Bayern of Jupe Heykens (which made the treble and terrified everyone), then City with the best players in the world and their endless rotation. Yes, he is good, but against the background of the opportunities that he had, the results are quite ordinary or even modest.
I absolutely disagree. If about Barcelona, which was Guardiola's first coaching experience, as well as Bayern, which has been the absolute leader of German football for many years, we can still somehow downplay the influence of Pep on the formation of the team, then this cannot be said about Manchester City. It is no exaggeration to say that it was Guardiola who made a relatively ordinary club, which Manchester City was before, first the undisputed leader of English football, and now European and world football. I am also not very enthusiastic about clubs that buy up the best players and become leaders thanks to this, but Manchester City is still a coaching team and here you can see the hand and style of the master of his craft, which Guardiola has already become.
Firstly, from any "ordinary club" you can make a top club if you pour in billions of dollars. Even if you create a club completely from scratch, there will be a result. Secondly, City were champions before Guardiola and they will be champions (if they are still not punished for fraud) after him. I don't see that Guardiola is the backbone of City's success - the real backbone is money.
