Manchester city have had their dominance and they've enjoyed it, though it hasn't been so without a competition from others especially Arsenal and Liverpool, so am not surprised that they are sharing the odds with other elite clubs. Hence as a team and your showing superiority, other clubs will always look for a way to tackle you just to reduce your dominance and so far this is what Manchester city is experiencing at the moment, trust me even next season isn't going to be easy with him.
The Premier League doesn't just belong to Manchester City other clubs have the right to break Man City's dominance so the EPL isn't seen as a farmer's league. Strong competitors like Arsenal and Liverpool deserve to make things difficult for Man City. Furthermore, last season, Man City experienced an injury crisis that caused the club to decline, creating an opportunity for Liverpool to win the EPL title.
Next season, things won't be easy for Man City as competition in the Premier League is getting tighter. Chelsea might enter the title race between Man City, Arsenal, and Liverpool, so get ready for a very interesting season.
