Manchester City are better than other teams in terms of squad quality. Teams like Manchester United, Chelsea and Liverpool cannot easily catch Manchester City no matter how many transfers they make. At this point, I think the talents of the coaches will come into play. And I guess Klopp's Liverpool will be the only team that can challenge Manchester City. I think Manchester City will be the biggest championship candidate of the next season. But the team that can push them will be Liverpool. It is too early to talk about the next season already. But it could be Klopp's year. Because the only way to catch Manchester City depends on the skills of the coaches. We saw this in Asenal last season.
Jurgen Klopp is still worthy enough to show the best strategy by competing in the Premier League against Manchester City. I also agree with what you said, for next season a club like Manchester United still cannot reach a point where stable performance is owned. Moreover, Chelsea who at all for now Chelsea will only focus on the development of the Squad so that they really show each other compatibility between players and coaches. One club that may still be able to show ideal performance includes having the potential to give Manchester City a bit of a fight next season namely The Gunner. Even so, I'm just trying to be optimistic about what Arsenal did with Arteta last season so that the results can still be improved and it will become a club that is worthy enough to challenge Manchester City.
One fact that most have forgotten about the Manchester City squad is that despite the fact the club spent so much money to buy them, they weren't assembled in just one transfer window. Before the arrival of Erling Haaland, the club was lacking a world class striker. The quality in the squad is a result of several good transfers over the years.
Liverpool is the club that stands a better chance to challenge City but that doesn't mean that they're City's match in terms of quality. The new English Premier League season is yet to start but City are clearly the favorites to win it again
