Firing Guardiola? It would be a huge mistake. There isn't such thing like you can have a perfect season every year. Manchester City clearly need some big changes in the squad from now on.
De Bruyne is horrible unfortunately. He isn't as good as he was in the past anymore.

The best for him would be to leave immediately. There are many more useless players to be sold this season.
First I thought it could be because of concentration problems. But no. Some players just don't want to play. We saw it yesterday. Doku must be really disappointed with his teammates as he was the only one making a real effort.
City firing Pep Guardiola would undoubtedly be the beginning of their downfall. While the team has struggled this season with a series of disappointing performances, I believe the solution lies in strengthening the squad rather than changing the manager. To return to their best, City must bring in quality players who will be able to add both depth and skills to the team. A well structured transfer plan will be needed ensuring the right signings and that they don’t break the FFP regulations.
