Villa slipped to defeat against the Gunners, who scored either side of half-time.
The hosts took the lead two minutes before the break when Jack Jebb converted from the penalty spot.
Then, on 61 minutes, Tarum Dawkins scored to double Arsenal's advantage.
It means the claret and blues are still waiting for their first win over 2014.
The Villa young guns are back in against West Ham at Bodymoor Heath on Saturday.
