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.
Is Arsenal short of players? Arsenal have 10 defenders and 6 midfielders and strikers in their squad. Arsenal have enough players. Arsenal should now make a decision to give the necessary players a place in the squad and sell the extra players. There are several players outside the main Arsenal squad who are not able to perform well enough. Therefore, Arsenal's performance becomes erratic whenever any important player of Arsenal gets injured. Arsenal management must definitely consider this aspect before buying players this season.
Having numerous players isn't what they need to better their performance they need quality players in the team, take Saka for example, can Arsenal with it's current squad right now survive without the presence of Saka? It's difficult for Arsenal to win matches when Thomas Party is not in their games so they need more players like the two players I mentioned then part ways with the other players so that the team can improve on their performance and also hope of getting trophies next season.
