I think Arsenal and Manchester City are the teams that are not affected by a lot of crowds because they played in front of a lot of fans. As a result of playing this match, they learned how to play under pressure. Even though Manchester City has the advantage, this will be a match that the better team will win.
It has a small or big influence, but it cannot be denied that playing at home makes a team have better motivation and self-confidence, whereas the visiting team will be under a little pressure.
Likewise with Arsenal, even though they are a big team, it cannot be denied that the support of Manchester City fans will make Arsenal's mentality decline a little, especially since this match is very crucial for the two teams who are competing in the race for the Premier League title this season.
