Arsenal midfielder Tyrell Robinson scored twice in the U18's 3-1 win over Brighton.
Robinson put the hosts in front before Luis Garcia levelled the scores just six minutes later.
He scored again after the break before Yassin Fortune added a third in added time to secure the Gunners' third straight victory.
Frans de Kat made three changes to his starting XI, most notably bringing midfielder Reiss Nelson back into the team. Nelson hit a hat-trick for England U17 last month against Armenia.
