The game is not easy for Man City nor Arsenal but both want to put on a great show to win the game and Ederson absence causes a lot of trouble for Man City. Man city is very dangerous but Arsenal does not want to Lose the top position.
When Manchester City and Liverpool draw then Arsenal at that time who benefit by rising to first place in the league, but later maybe we will see it happen again in the Arsenal vs Manchester City match and most likely also Liverpool will benefit from the game by returning to the top of the table with a note Arsenal lose or draw and Liverpool win in other game, Currently Liverpool who are in second place in the standings have the same points as Arsenal and Arsenal are only ahead of Liverpool on goal difference at this time.
Before facing this crucial match, Arsenal today will try to have a match that is no less important in the Champions League and if they win later then Arsenal can look at the game against Manchester City with high motivation, if you say if Manchester City lose Ederson then it looks like Arsenal will also not be strengthened by one of their star players who may still be injured, namely Martinelli, So I think the current team is quite balanced even though actually Manchester City have a better head to head than Arsenal so far.
