Ghana’s King Osei Gyan was on target for Norwegian side Viking as they lost 4-3 away to Europa League campaigners Tromso.
The former Fulham youngster netted in the 53rd minute to make the scores 2-2 after Andersen, Moldskred and Olsen had traded goals for both sides.
Viking coach Jonevret made two changes at half-time and it was not long before they reduced the deficit through Trond Olsen, before striker Gyan leveled the scores.
Tromso substitute Veton Berisha shot his side into the lead before Zdenek Ondrasek equalised to make it three all.
Jaroslaw Fojut grabbed the winner for Tromso in the 82nd minute.
