Arsenal direction of play has begun to improve rapidly since Arteta led the team on the sidelines, he has succeeded in making Arsenal a team capable of providing competition for the title. The failure to win trophies in the last two seasons means that Arteta needs to improve his team's abilities so that they always perform optimally. They must consistently maintain their performance because the team that are their competitors always maintain their performance well.
Arsenal failure to compete with Manchester City in the last two seasons must be overcome immediately by increasing the team's strength so that the game is faster and produces more goals. Currently Arsenal only target is winning the title, they will try to win the EPL title while breaking down Manchester City's dominance which has lasted four seasons.
Arsenal level of competition is very high, and they are really trying their possibilities to see that they get a trophy, but unfortunately they are always failing to do that at the end of the season. Although to me, getting more players is not compulsory like for other teams because Arsenal's squad is full of strength and everything is complete, I think they just need to change their pattern of play and some other things because even weak points I did not see from them, but their main problem is winning a title, which they need to win seriously.
So since all they need now is to win a title, they need to come back with a new pattern of play so that they can be able to concur with Manchester City's dominance. It is only Manchester City's performance that always holds them back from winning the title.
