I totally agree with you. Letting go of Pep would be a huge mistake. He is the reason City has been so dominant, and even though this season has been rough, replacing him isn’t the solution. The squad needs reinforcements, not a new manager. A few key additions in weak areas could help City bounce back without disrupting the stability that Guardiola brings.
I share the same thoughts with you. It would be a very big mistake to sack him because of one disappointing season. I know some persons may think his divorce saga could be responsible for the club's poor performance, but they should not forget that City sold some key players without replacement and also Rodri's injury really affected the team. Based on what he has achieved for the club I think he deserves atleast one year to get them back to where they belong. But If he fails to do this after another chance, then they can part ways with him.
They won't sack him, but lots of things are happening in Guardiola's life. He is now getting divorced from his wife and frankly, I sometimes thought he is busy with other things in his mind. Usually he is going crazy on the sideline from the first to the last minute, but this season he was absent sometimes and the whole team didn't work together very well.
Now I think he will make a cut in his private life and fully focus on Manchester City once again because I doubt that he wants to leave his legacy behind with such a disappointing season. The Champions League is still very high on his list and he wants that title certainly once more.
