Manchester City is currently in top form and they are also competing fiercely in the race for the Premier League title this season so in my opinion the percentage of surprises is very small and also Chelsea's current performance is also quite bad, in terms of quality of course there is a significant comparison of strength between Chelsea and Manchester City.
Looks at the form of Kevin de bruyne and Phil Foden, they are firing in top form and Haaland hungry. Chelsea are done for! there is no way Manchester City will not win that game and possibly embarrass Chelsea in the process. Palmer will not perform, Pep knows his weakness and the exact player that can bully him. Manchester City will score many goals against Chelsea. Eyes will also be on West Ham to see if they can bounce back from their loss to Arsenal, they were humiliated, Nottingham Forest is not also an easy opponent for them, they may also loose in that game.
Whenever you see some players like De Bruyne and Haaland are in good form and they had good performance in Manchester City you can expect to see perfect performance from this team. Manchester City was getting far from the top of the table and they had been having bad performances recently in the premier league and even other teams like Arsenal and Tottenham got better results in the first games but since De Bruyne backed in the field they are again backed to the good form.
