I don't even know which line Arsenal needs to improve. because last season everything looked extraordinary for Arsenal. Their only weakness is the players' mentality. Oh yes, they need to have more options on their bench so they can still compete without worrying about not having enough players when injuries occur.
Of course, Arsenal has a problem with the players' mentality. It makes them to lose many points in second half of the season. I think Arteta already has a plan to solve the problem. Arteta must know well Arsenal because he already managed Arsenal since 2019. Let's see what Arteta will do in the next season.
So this is quite an influence on the consistency of Arsenal's play in the last few seasons, right? Because usually, Arsenal looks very enthusiastic and even very positive when they have to compete with several clubs, so that they often lead the standings very well. It's just that, suddenly they will drop again, and if they have already dropped, it will usually be quite difficult to get back up again.
Moreover, it is reported that several of Arsenal's top players are being targeted by other top clubs, Saka by Man City and the other, Lintasa by Real Madrid. Will this idea of yours actually happen?
Oh yes, there is good news that their player Jurrien Timber this season will start to be able to compete again and return after injury. He was a signing last season but was not able to strengthen the team optimally due to injury, and eventually he will return. Yes, I hope the injury doesn't have much of an impact on the quality of his game in the future.
