Sacking him is not the best thing because seeing a manager as good as him will be difficult so they should be patient with him until he figures out what is wrong and find a solution. I don’t think players are the problem, he is not the only team that suffered injuries and he should know that injuries will certainly occur and should be prepared for it, in the past seasons his players suffered injuries and still was able to manage the available ones so i don’t think it’s the injuries. He needs to recruit more players especially wingers because Doku and Savinho are not up to standards and haven’t been contributing enough. We will see what will happen if Rodri joins the team back.
Firing Guardiola would be a bad decision for Manchester City management. Let's not forget that Guardiola is the main architect behind making Manchester City the best team in the Premier League. Guardiola is a very experienced coach. With the help of Guardiola, we have seen City's dominance in the Premier League in the last few seasons.
I would say that Manchester City should prepare a big fund now. There will be a lot of changes to the squad in the next transfer window. In particular, it is very important to strengthen Manchester City's defense and find a worthy replacement for Haaland.
