Viking vs Lillestrom prediction (Over/Under)

Viking have played well in scoring recently, they have found the net twice in the latest home match against Stabaek and I expect them to score more than once against Lillestrom that are weak in defence with 36 goals allowed in 21 matches played. Still Lillestrom have solid offense that is averaging 1.5 goals per game. They should also score as Viking have conceded twice in each of their latest three matches and are seven games without a clean sheet in the league. Viking and Lillestrom have met once this season and have played attacking football in that game. Theyhave combined 31 shots and the match ended with three goals and I wait for another high scoring match where even more goals might be scored.
