Statistically they look the same, so this is really not an easy match for them. Both Chelsea and Manchester City need a win to maintain their position. But in terms of appearance, they can also be said to be the same when we look at their statistics in the English League this season.
However, Manchester City has another advantage, yes they will play as hosts and usually the team that plays as hosts is more favored to win the match. On the other hand, they also have to play a match in the Champions League first which will be very draining.
Not much different but in the last few matches Manchester City has been slightly better even though they lost to PSG in the Champions League. Another advantage is that the match will take place at Manchester City's home ground so their motivation to win is much greater because they are playing in front of their own audience. Chelsea will try to get points in the match because if they lose it will affect the standings and I think a draw is the best because both teams will definitely play more carefully so as not to lose the opportunity to get points.
