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.
Why will Manchester city even think of sacking pep Guardiola just because his performance dropped this season? I don't even think the management will make the mistake of sacking pep Guardiola, because if they can do that, they are going to regret that. Pep Guardiola have been performing well at Manchester city for years, he made then what they are today, so just one season decrease in performance shouldn't make them make that kind of decision. What the management should do right now is just to work with pep Guardiola, and look for how they are going to improve the teams performance.
I know Manchester city performance has dropped, but its not so worst that they will sack pep Guardiola, a coach that has won four premier league title in a row for Manchester city, why will they even think about sacking him just because of a season, they should just allow him fix the club, because its going to be difficult for a new coach to fix Manchester city.
