Pep's contract will be running out next year. The primary issue arises if he decides not to extend his contract. Numerous players are still staying at the manchester city caused by pep. I can imagine if pep will not be there again and there will be many players to leave from there.
Pep is the main reason people are staying in the club. It is caused by people knew him as one of best coach in the world. Manchester city needs also to prevent the worst thing that may happen in the club.
I think that haaland and any other important players will not stay in manchester city if there will be no him in city.
City's performance is very consistent but we must also admit that chelsea was so strong in the previous match. City has been using all of its power but chelsea is playing with all of its spirit. No doubt if city was getting draw against chelsea.
The result is not that bad but losing two points are still bad for manchester city. Chelsea is very strong right now
City were champions before Pep and will be champions after Pep. You are exaggerating his importance. And I doubt that there will be many players who will decide to leave a dominant club that pays them huge salaries due to a change of coach. Although, for example, Gundogan left for crisis Barcelona without any particular reason (and no Pep kept him).
