I don't think Manchester City's rivals are waiting for Pep to leave (some are but not all) so they could take that opportunity to be at the top as always, no. Pep Guardiola's presence is what's making the EPL and winning the title more challenging and if as a coach you feel you're good enough then win the title when the best is around not wait for the best to be eliminated from the equation before calling yourself a good competitor. If he should quit his position as the City boss I would like to see him coach a national team let's see if he can keep up with the pressure of coaching a national team.
Yeah right, the dominance of Manchester City will definitely end up just waiting for time and we know that no team can maintain glory for decades, now we can see how Manchester City has a gap and also competitors can catch up 2 draws 2 defeats are proof that they have a problem. I have estimated that Manchester City will go through the golden era and the other team will replace them, Chelsea and Arsenal might be the next best team for the next 2-3 seasons.
Manchester City's dominance is not that good at the moment, it is true that no team can maintain their glory for decades. The current situation of Manchester City in which they may have a lot of competition this season proves that they have a gap. Looking at the current position of Manchester City, we can say that they must have problems or they will have to go through a golden era. Yes, Chelsea and Arsenal may be the best teams for the next seasons, but currently Liverpool are more likely to be selected as the best team of the season.
