Chelsea will need time this time to learn a new style of play. Sarri is going to teach his football, and it will take i reckon more than 1 year to do so and be competitive.
City are the favs to win it, as it is always with the current holders, BUT everyone knows which is the team coming (and it's not United with pathetic Mou running the team): it's Liverpool of course. They are CL finalists, lost only Emre Can, retained all their world-class players, and added some world class quality in Alysson, Keita and Fabinho.
If city is going to lose the league, the only team they can lose it to is Liverpool..
PS: Kante is an absolute machine! It's a pitty the incapacitated Barca board is not even considering spending the money they had allocated for Griezman to get Kante. Busquets alongside him will permit multiple variations of deadly attacking combinations of the 4 front players including Messi...
