Analyzing the current form of the teams, we can expect a more defensive game with a low number of goals. Tromsø is struggling in attack and defense, conceding 15 goals in 7 matches. Rosenborg has also faced difficulties, losing to KFUM in the last match. Both teams have been not very efficient in recent games. Therefore, I predict that the Tromsø - Rosenborg match will be low-scoring, and I bet on Under 3 goals.
