Zak Ansah and Josh Rees both scored twice as the Under-18s beat Chelsea 4-1 on Saturday.
Ansah opened the scoring after just four minutes and Rees doubled the lead 15 minutes later.
Rees added a third just before the half-hour mark as Arsenal cruised to a three-goal lead before the break.
Aziz Deen-Conteh pulled a goal back after 74 minutes but any hope of a comeback were extinguished when Ansah sealed the win with his second three minutes later.
