Manchester City's dominance is very difficult for other clubs to break and in the previous two seasons Arsenal were the closest competitors, but they failed to break Manchester City's dominance. Manchester City prepares their team very well and they have a coach who is visionary and can always solve problems even though several of their important players are injured. If you look at the Manchester City squad, maybe there are several clubs that can dominate when key players are injured.
But this is difficult to do because Pep Guardiola always has the option to choose players every time they compete. Next season we hope that there will be several teams that can compete with Manchester City and hopefully they can break the dominance that Manchester City has held for so long.
At this point, I think people are just waiting for City to lose their dominance themselves. Look at Bayern, Leverkusen had amazing results, but Bayern sucked all season long too, lost to Leverkusen terribly. I think it is clear that some team will do great one day, but also clear that we need to see City start doing not so great eventually. For the time being, it is a "failed season" for them when they win the premier league and nothing else. Which goes to show you that they are way better than anyone else.
Winning premier league would be the biggest achievement any other team could dream of, it is not even an achievement for them, hell fans did not go out to celebrate that much, it was just a few thousand people. Imagine being bored of winning premier league.
