On a historic night at the Progress with Unity Stadium, the Reds dominated the possession stats and shot count against the Norwegian champions.
United were frustrated for long periods by the visitors, who seemed happy to defend deep and force us into taking efforts from distance.
The key moment came after half an hour, when Julia Zigiotti Olme's pass was ruled to have been handled by Arna Eiriksdottir in the area.
Captain Maya Le Tissier stepped up from the spot and coolly sent Tove Enblom the wrong way.
That matchwinning contribution proved enough to top our post-match poll, with our centre-back claiming 51 per cent of the votes.
