In my opinion, Chelsea and Liverpool are the biggest contenders for the title. They have a very strong squad, at least in my opinion, I see Chelsea as stronger than Manchester City, Arsenal, Manchester United, Tottenham, and many other clubs. The Chelsea coach took a long time to make many signings and experiments until he got the ideal squad. I'm even surprised that Manchester City didn't do the same thing in this transfer window.
Maresca has not been working with Chelsea for very long, but he has already managed to achieve good results in just one season. I think it is still too early to assess the strength of the teams and to say that Chelsea are stronger than Arsenal and City, I have my doubts about that. As for City, I cannot assess them until they start playing official matches, that will also be the moment of truth, which is why many are waiting to see how capable Guardiola is of leading the team out of a crisis.
