Arsenal U18 coach Jack Wilshere praised Ismeal Kabia after their win at Aston Villa.
The Gunners won 3-2 - thanks to three penalties on the day.
Wilshere later said: Kabia was brilliant.
"I remember after the Derby game when he came on and made an impact by scoring the winning goal.
He's shown his quality over the last few weeks in training and has been pushing me to start the game. He got his opportunity today, and he was exceptional. It's always a good sign when the opposition defender gets substituted, so credit Kabia; he was outstanding."
