5) Andre Harriman-Annous

The striker’s debut came against Brighton & Hove Albion in October last year. He was named in the starting lineup for the Carabao Cup tie by manager Mikel Arteta, to the surprise of many.
Harriman-Annous lasted 77 minutes and gave a good account himself, but he has only managed one further appearance since then.
The teenager came on for the final 10 minutes of the 3-0 win over Slavia Prague in the group stages of the Champions League last campaign.
Harriman-Annous has subsequently made the matchday squad for four other fixtures, including the FA Cup quarter-final against Southampton, but he hasn’t been used by Arteta so far this season. He did, however, score against senior opponents for the Under 21s against Leyton Orient in the EFL Trophy a couple of weeks ago.
