Regarding Liverpool, I also think they may have a slump now, and it is not yet clear how Guardiola will be able to prepare City. Arsenal are fine, Arteta will be aiming for his first trophy, but this will only be possible if other teams have slumps. As for Chelsea, for me they remain a dark horse, to be honest I do not believe that they are capable of fighting for the title this season, but who knows, maybe they will surprise us again.
I think that after this boost of self-esteem they have received, they can actually do very well and they have demonstrated this by beating the winner of the Champions League in a one-off match and not just the last team to arrive in their league, so I think they can do very well if not even win the championship.
