Arsenal look in good shape to reach the Europa League semi-finals after deservedly beating Napoli in the first leg of their last-eight tie.
Aaron Ramsey converted Ainsley Maitland-Niles’ pass to finish off a good team move and give Unai Emery’s side the lead.
Kalidou Koulibaly then scored an own goal when he deflected Lucas Torreira’s shot past goalkeeper Alex Meret.
The impressive Meret stopped the Gunners winning by more.
Napoli, who are second in Serie A, host the Gunners in the second leg next Thursday at the San Paolo Stadium.
