Arsenal began the Europa League knockout stage with a convincing 3-0 win over Ostersunds in Sweden on Tuesday.

The Gunners were off and running in the round of 32 after just 16 minutes through defender Nacho Monreal, who pounced on a spilled save attempt by Ostersunds goalkeeper Aly Keita and slotted into the gaping net from close range.

Arsenal went 2-0 up 11 minutes later when a fizzed-in cross from Henrikh Mkhitaryan deflected off the back-side of defender Sotiris Papagiannopoulos and beat a helpless Keita, who was left no time to react in the Ostersunds goal.
