Rather than recruiting players who already have a name, I see Arteta could be better when he develops young players, and that's what actually brought him this far. So this must be thought about by Arteta, some of the players he brought in did not show the contribution according to expectations, not bad, but could not significantly lift the team's performance either. So maybe he can do options such as looking for young players, or recommending young players to be part of their squad. But the risk is that the process will definitely be quite long and can also be successful or not, but he must be able to decide something.
Arsenal management should add more players to their squad. Arsenal squad has less talented players. That is why Arsenal's performance is erratic after the injury of important players in the squad.
I don't think Arsenal will benefit much by adding young players to the squad. I think Arsenal management's goal is to win the Premier League title. Despite performing well in the last few seasons, the team has failed to become champions. If they add young players to the squad, maybe after 2/3 years Arsenal will be able to form a strong squad. However, if they want to do well in the recent times, they must add talented and experienced players to the squad.
