Not only Chelsea, Manchester United should also be considered. Manchester United is a team that has been pretty solid under Ten Hag, so you shouldn't ignore them either. I also know Chelsea are looking for a way to be in better shape, but Pochettino needs big time and support.
Chelsea could still fail if Pochettino's strategy and plans don't pan out in the first season, but they are a team looking to move forward. Apart from that, Liverpool will also try to show their class and Arsenal also look very dangerous.
That's a good consideration from Man United, judging from what Erik Ten Hag has done, Man United is indeed much more solid and now they are bringing in several players, currently they are also eyeing Inter Milan goalkeeper, Onana.
Liverpool recently brought in Szoboszlai from Leipzig, of course Liverpool is improving their squad, they will improve from this season.
Chelsea, we'll see how it goes after throwing a lot of players away, Pochettino always has a plan he wants, I think it's a matter of time.
Arsenal have also improved in terms of squad, the main thing is that in August this league will be more competitive and have tough competition from many clubs.
All the teams you mentioned above deserve to be called candidates in the race for the Premier League title next season. My biggest doubt at the moment is Chelsea, but that might just be on my side. Meanwhile, Manchester United I always expected to do better season after season, but so far they have found the right way to get back there.
The favorite in the Premier League is still Manchester City, yes, but I don't expect him to dominate the Premier League every season. It's not good to see Manchester City win the title in 4 consecutive seasons, and Manchester United should be able to break that chain next season.
