Daniel Nannskog opened the scoring in the 51st minute with the away side's second not arriving until the final minute when substitute Johan Andersson was on target.

Stabaek's win maintained their unbeaten start to the season after seven games and kept closest rivals Fredrikstad at bay after they thumped Aalesund 5-0.

Gardar Johannsson scored a first-half double after Fernando Wallace had broken the deadlock on the hour mark to put the home side in complete control.

Tarik Elyounossi and Abgar Barsom completed the rout after the break.

Reigning champions SK Brann have endured a subdued start to the defence of their title and had to wait until Thorstein Helstad's 77th-minute strike to claim a 1-0 win at home to Valerenga who had Dan Thomassen sent off after 65 minutes.

Brann are six points adrift of the leaders.

Rosenborg revived their flagging fortunes with a 4-0 hammering of Lillestrom.

Norway's most successful club had managed just four points in six games to sit near the foot of the table but goals from Marek Sapara (23), Per Ciljan Skjelbred (52), Steffen Iversen (55) and Yssouf Kone (66) gave their fans renewed reason for hope.

Bodo/Glimt maintain third place in the table after goals from Thiago Martins (33) and Trond Olsen (90) helped them to a 2-0 win against Tromso.

In Friday's other game Viking FK twice came from behind to steal a 3-2 win at Molde.

Jose Roberto Mota had twice given Molde the lead in the second half, only to be pegged back by goals from Martin Fillo and Andrius Velicka.

Velicka scored the winner two minutes from time to clinch victory for Viking.
