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.
They are seriously in need of players and that is one of the things that is affecting there players that they are unable to perform very well, they need fresh blood and instead of arteta going for attackers his busy defenders having defenders is good but balancing everything is very okay and when the club is balanced in all positions then the impact will be felt.
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.
They will benefit from adding players but it is not even about young players because sometimes this young players don't have any experience and already people have believed in them, it is better they go for a player that is experienced and will give them exactly what they want, from last two season them became Manchester City rival and I was already thinking that this season we are not performing well arsenal will be the one to take advantage of this whole situation not know Liverpool was the next in line and arsenal really disappointed a lot.
