Strikes from Arild Sundgot (24) and Magnus Myklebust (32) and a Benjamin Kibebe own goal (28) put the visitors 3-0 up before Magnus Kihlberg (54) grabbed a consolation for the home side.

The win lifts unbeaten Lillestrom onto 13 points after five games, while Aalesund are still waiting for their first victory and have just a single point.
