It's a tough one for Gunners and very much possible that City might be able to pull of a win here but Gunners have improved a lot and at this point they are the only one close opponent to City. Rest are not that consistent so I am really hoping for an Arsenal win here as this will change the title race exciting from the beginning. We need some change in our tactic a bit and suprise City with our performances and I hope Arteta has something special planned out for the game against City.
After the defeat in the Champions League, this was a major blow for Arsenal, the team nicknamed the Gunners had not been defeated in several weeks, the team led by Mikel Arteta did not drag on or mourn the defeat for a long time, another match was waiting, and the schedule was so busy that players need to maintain extra stamina, there are several injured players in the Champions League, this will make Arteta worry about the next match against Manchester City, Arteta has to change tactics in the match scheme later, which player is suitable for the match later, only Arteta can know the potential of each player, playing and being supported at home creates enthusiastic motivation in chasing numbers in the Premier League standings.
I think they have enough players still to cover up for the injured player so not a big worry for Arteta if you ask me. Lot of players are very adaptable to other positions so Arteta has a very good set of options to choose from. But I feel it's better to develop other players as well by giving them chances. That way they can also help in matches in a better way and create a strong team.
