The EPL is a very competitive league where no one particular team dominates every season. In other to make it up to top 6 to play European competitions you have to ensure balance in the team and keep consistently performances. Chelsea and Arsenal fc were a lot shaky at the last weeks of the season and really need to put in work to do better next season
Which league are you talking about? EPL has been dominated by City for nearly 5 years now, and Liverpool is right there as well, they won one in the middle there. I mean I am not saying that there is no competition, of course there is one, for each spot, but domination is there as well. I believe it was last year, for one point City went 20 games winning streak right?
I am not entirely sure how many games it was, maybe more than 20, but they dominated EVERYONE at that point. This is why I highly doubt that anyone else would say that EPL doesn't have any domination, there are many proofs that City is dominating it and there are barely any competitions to them, maybe LFC time to time.
