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.
As the club's most successful manager I totally agree with your opinion that sacking Pep Guardiola would be a huge mistake by Manchester City's management. He's achieved so much with the club in his 8 seasons as the club manager by winning the English Premier League 6 times, 1 UEFA Champions League trophy, 2 FA Cup and 4 League Cup trophies. That said, I don't think they can also do much of the Spanish manager decides to leave at the end of the season probably because of his poor results with the club this season. In all his managerial career, Guardiola haven't finished in a position less than 2nd but he's very likely to do that this season and if that happens, he might consider leaving the club at the end of the season.
