Cedric Soares played 69 minutes for Arsenal in Tuesday's EFL Trophy victory at Exeter City.
The Portugal fullback was the one senior player to feature as the Gunners hit five past their opponents.
Cedric has struggled for minutes this season and was happy to drop down and guide Arsenal's kids to their victory.
Seb Ferdinand struck twice coming off the bench, with Charles Sagoe Jr, Jack Henry-Francis and Khayon Edwards also scoring.
Over 3,000 fans attended the tie at St James' Park and Arsenal U21 coach Mehmet Ali said: "The atmosphere was quite different from what we typically experience in Premier League 2, and we faced resistance from the home crowd as the away team."
“I want to give a big shout-out to our supporters who made the trip tonight. They were absolutely brilliant, providing unwavering encouragement of support throughout the game."
