#3 Folarin Balogun
The recently turned 18-year-old was extremely impressive across the academy sides last season scoring 28 goals and assisting five times. This has continued into this season with Balogun scoring three goals and getting one assist in his first two under-23 games of this season.
With Eddie Nketiah out on loan at Leeds United, one could see Balogun get a chance in the Europa League and the Carabao Cup.
#2 Robbie Burton
Robbie Burton impressed for Arsenal in the pre-season tour making a handful of solid appearances for the first team. This has led many to believe that Unai Emery will give him a chance in the first Europa League game of the season on the 19th September.
Many also believe that if he is given a chance this season in both the Europa League and Carabao Cup it won't be long until he makes his debut for Wales.
#1 Bukayo Saka
Bukayo Saka made his debut for Arsenal aged only 17 during last season in the Europa League and then even went on to make his Premier League debut as well. In total, he ended up making four appearances for the first team last season.
So yes you could argue he is already part of the first team but Saka be given a chance to play on regular occasions for Arsenal in the Europa League, Carabao Cup, and also FA Cup.
