I am actually not still clear on this, if pep guardiola is leaving Manchester city or he is staying, because it's already been speculated that he is leaving this summer, but if truly he is leaving, it's definitely going to reduce the dominance of Manchester city in the English premier league, but if he stays put, then I believe that the dominance of Manchester city will continue, because aside arsenal, I don't see any of the remaining team in the English premier league challenging Manchester city to the title.
If you look at Liverpool and Chelsea, they just recruited a new manager, so they will obviously needs time for them to instill their ideas into the minds of their players, and as for Manchester united, their is nothing special about them since sir Alex Ferguson left the club 12years ago, they are just struggling, so I believe that it's still going to be between Manchester city and Arsenal regardless of if pep guardiola leave or he stays.
I think Pep Guardiola would love to set more records with the Premier League's best team at the moment over the next few seasons. Pep Guardiola is the most influential coach in Manchester City's achievements since he arrived, so the president or club owner would definitely be happy to give him a longer job except when Pep Guardiola no longer feels comfortable staying at Manchester City.
I agree that if Pep Guardiola stays at Manchester City for many seasons to come, then he will most likely continue his dominance in the Premier League. He has proven that by winning 6 titles in 7 seasons, so if he stays for the next 5 seasons then he will probably win 10 titles.
