The youngster was just 15 years and 181 days old at the time and became the Premier League’s youngest ever player and Arsenal’s youngest in any competition in the club’s history.
He also netted three times in the Gunners’ Carabao Cup campaign and has scored his first Champions League goal as he becomes a fixture in Mikel Arteta’s match day squads.
That early appearance attracted the attention of Manchester City, with the Premier League champions becoming interested in the teenage star.

Legendary Arsenal boss Arsene Wenger has compared Nwaneri to the man who had previously been the club’s youngest ever player, Cesc Fabregas.
