Thanks to Pep Guardiola, Manchester City can get a strong performance foundation so that they become a team that is really difficult to beat. Pep Guardiola's success has made Manchester City lucky because they have found a coach who is suitable for them so they can win consecutive titles and of course that is a very good achievement. I don't think Manchester City will experience a decline in performance if Pep Guardiola is still with him, of course with Pep Guardiola's guidance.
Pep Guardiola has made a big contribution to Manchester City, because Manchester City, which is coached by Pep Guardiola, has made them lucky because the guidance and direction he gave them succeeded in making Manchester City a strong team. But you need to remember, no coach will stay forever, so when Manchester City is left by him, I don't know if Manchester City will find a suitable coach again so that they can still remain consistent or they will experience a decline in performance.
Manchester City is currently the most dominant club in the English league, even they have set a new record as a team that has managed to get 4 trophies in a row in the English league so far, I personally agree with you a little, but maybe the view we have is a little different in looking at the revival that has occurred in Manchester City so far, Before Guardiola came, actually Manchester City had been able to become a contender for the Premier League title because indeed since the takeover by Syech Mansour, of course Manchester City have strong finances in building a team until today, the financial ability owned by Manchester City today is certainly the main factor of Manchester City success.
Indeed, the role of Guardiola also cannot be separated from the success of Manchester City at the moment, but I think financial strength is actually the main factor for Manchester City to dominate the Premier League, when the coach gets full support from the management of course it is not difficult for him to make the team quite great and I think Guardiola got all that at Manchester City, reportedly, currently Guardiola only has one more season left to coach Manchester City and there is no sign if a new contract will be signed soon, so it is likely that Guardiola will leave Manchester City after his contract expires later, I personally hope that Guardiola in the future can handle a team that has not as good finances as Manchester City, so that we can see how much he is capable of coaching a team without support strong financial.
