Arsenal can level up with Manchester City if they don't lose too many matches because initially now Manchester City is just gapping Arsenal with 2 points which can easily be countered if Manchester City loses and Arsenal wins and since the season is still new we should not just draw conclusions from the early matches played so far because they still have a long season ahead. Arsenal match against Brighton was really tough and if not that Arsenal were so determined in that game they would have lost to Brighton and red card affects the performance of a team so much so for the fact that Arsenal managed the red card Declan Rice got at the early part of the second half and could not lose out even with the pressure of Brighton.
Arsenal already has a strong defence that will be their backbone in all the games they are playing because, if not for that, they will not have gone any further in this season, but one thing we need to consider in this season is that there is a higher possibility that Arsenal will be the next option to take the trophy home. because Manchester City is not a threat anymore to them, which makes them a threat for Manchester City because if they didn’t focus more, this season will be very hard for them to overcome.
Furthermore, about the game between Arsenal and Brighton, everyone knows that Arsenal really tried their best to maintain the game on a draw because Brighton were very strong after arsenal got their read card. The pressure was so high for them, but they were trying their best to the end of the game.
