However, despite the lure of bringing in outside talent, there are some players in the North-London club's academy that will be itching for a chance to get into the first team and in turn, help the Gunners to have certain options ready as per condition.
Here are three youngsters who can step up to plug certain necessary gaps in the Arsenal squad...
3. Joe Willock
Joe Willock's big moment for Arsenal came was when he was brought on late in the Europa League final last season, in place of the ineffective Mesut Ozil.
Although the game was out of reach for the Gunners by then, the youngster was more effective in the 10 minutes he played than Ozil in the remaining 80.
2. Jordi Osei-Tutu
Arsenal have been suffering at the right back position for quite some time now, with only Hector Bellerin being a reliable option.
With both Carl Jenkinson and Stephan Lichsteiner set to depart, Osei-Tutu can prove to be a good option to have alongside Ainsley Maitland-Niles until Bellerin can return from his long-term injury.
Osei-Tutu can take over full time as Bellerin's deputy while Maitland-Niles can probably finally play in the midfield role that he craves.
1. Reiss Nelson
Reiss Nelson spent last season on loan with Hoffenheim and although his participation was limited due to an injury, he did show his prowess playing as a wide man.
Nelson scored within 14 minutes of his debut for Hoffenheim and managed a total of nine goals in nearly 20 games for the German club. He can be the one that Unai Emery can use on the wings, especially considering that the manager does not have many options to do with in that aspect and position of Arsenal's gameplay.
