AFC Bournemouth earned their first win against Arsenal as Jordon Ibe's maiden strike for the club clinched a comeback 2-1 victory at Vitality Stadium.
Hector Bellerin had put Arsenal in front after latching onto a superb Alex Iwobi pass and beating Asmir Begovic, but two goals in four minutes turned the match on its head.
Callum Wilson converted a perfect Ryan Fraser cross in the 70th minute, before the striker turned provider, controlling a long ball and teeing up Ibe to fire past Petr Cech.
The victory moved AFC Bournemouth from 17th to 13th, four points above the drop zone. Arsenal remain sixth.
