Arsenal needs to have more players that could help them to achieve their aim which is winning trophies, they have a good manager and their game play is fine but they are still lacking the ability to start off well and end the season in good performance.
I think what needs to be considered now is the mental condition of the players because currently Arsenal players are actually very many, even in the last few seasons Arsenal is one of the most loyal clubs in buying players because the club does not hesitate to spend quite a lot of money in each season, but when their mentality remains the same no matter how many players there are, the results will not change.
Although being runner-up is very good for Arsenal compared to the last few seasons, in the end this is not enough to answer the trust because it is clear that they are waiting for the trophy they got and until now Arteta has not been able to realize this even though the club has been very loyal.
So in this case I think it needs to be considered further now is how to manage their chemistry and mentality so that when their performance is good in a competition it does not decline over time and Arsenal's problems are always like that every season.
