Tromso IL have lost in their last Norway NM Cupen game, and their form is doubtful.
Although Tromso IL have home field advantage, they should not be overestimated.
On the other hand, Rosenborg are getting better in form, winning all of their last 3 league games.
The AH opening line is in favor of Rosenborg.
So the visitors are expected to win in this game.
