I agree that Chelsea should be able to win this week, even if they are playing away. But if Chelsea performance doesn't improve or they don't find points, then it will be very difficult to compete at the top for the champion zone.
Chelsea is currently in 14th place with only 4 points from the previous 4 matches. If the players' mentality does not immediately wake up then this season will be worse than the previous season.
Maybe everyone doubts Chelsea after seeing only the bad side, but in this match I will see the good side of Chelsea when playing away at home to Bournemouth and from the statistical results Chelsea can always beat Bournemouth even though playing at home Bournemouth will not be able to compete with Chelsea who more have better playing quality in terms of performance.
I can't avoid that there are always surprises as some people have said here, but those surprises will not matter in this match because it is absolutely certain that Chelsea will lead this match with a better score and can bring additional points to continue to improve the stability of Chelsea's performance.
