If you check critically five seasons ago, you would say that PEP guardiola's technical approach to games was not understood by a lot of coaches in England, in fact they were finding it difficult to tackle his tactical strength. however, over the years, clubs have slowly understood his approach on every match and even the least Club could easily stand tall to tall with Manchester City as at today. Giving the issue of his marriage that affected pep guardiola last season also, Manchester city's management would have advised him to take a rest, just so he could build this mental capacity again.
This is an important point. Guardiola's game plan is now understood by many coaches. And because of this, Guardiola is no longer able to perform as well as expected. Teams have identified the weaknesses of Guardiola's defense well. Manchester City have conceded 2 goals against Tottenham and Brighton and they have lost both matches.
Guardiola now needs to develop a new game plan if he wants to strengthen City again. Manchester City's squad also needs to be strengthened. Compared to Liverpool, Arsenal or Chelsea, Manchester City's squad will be behind.
I wouldn't expect much from Manchester City this season. If they can achieve the top four in the points table, that would be a good enough result for them.
