We overcame sub-zero temperatures on an artificial pitch to secure a healthy first-leg advantage in the Europa League round of 32.
On our first trip to Sweden since 1999, goals from Nacho Monreal , Mesut Ozil and an own goal - with Henrikh Mkhitaryan providing two more assists - have put us firmly in control of this tie. David Ospina's late penalty save also preserved a welcome clean sheet on the road.
The Swedes, managed by Englishman Graham Potter, were unbeaten at home in six Europa League games so far this season, but the Gunners were too strong on the night and we are firm favourites to progress now.
