After a sticky spell in the first half, Sead Kolasinac struck just after half-time to reduce Arsenal's deficit on the night against Ostersunds and extend their aggregate lead.
A minute of madness in the first half saw the Swedish minnows score twice to stun Arsenal and put themselves just a goal from qualification.
However, with Arsenal's quality going forward it was always going to be hard to keep them at bay and the 'Gunners' did enentually get on the scoresheet, though it came from an unexpected source and was rather gifted to them.
Ronald Mukiibi made a hash of clearing a cross from the right and the ball fell to Sead Kolasinac, with the big Bosnian lashing in at the near post to make it halve Ostersunds' lead on the night and extend Arsenal's aggregate advantage.
