Manchester city have good qualities players, and one of the prominent coach with lengthy experience in football space, with his presence everything is working smoothly for city. The citzyens performance will reduce without the master planner, Guardiola. He's the brain behind their triumphant prospects over the years, perhaps he got more achievements to accomplished. Manchester City will be too recalcitrant to let Pep Guardiola leave them so soon, after all he achieved the significant trophies that was the primary goals. He's a free man and he can decides to leave any time he feels the time is right.
But keep in mind that Pep Guardiola is an adventurous person, so there is always a possibility he will leave especially according to his statements if the club he loves calls, nothing can stop him from leaving and that club is Barcelona. Pep Guardiola will always be adventurous looking for new experiences, add insight and revive clubs that really need his services. Even though at this time Man City is comfortable with the presence of Pep Guardiola, it is likely that his departure will leave many gaps.
If Pep wants adventure he needs to go to a league he hasn't been to since starting his coaching career, and I think Serie A might be right for Pep Guardiola. He can meet and compete again with Jose Mourinho to conquer the league even if possible they can compete to conquer the Champions League.
Pep has experience that can bring Serie A representatives to win the Champions League
