The first leg in Norway ended 1-0 in favor of Bologna, and the Italian club is one step away from advancing to the next round. Vincenzo Italiano's side are enjoying a solid run, winning three matches in a row, but European matches are more important now. The Rossoblu are confident at home, and holding on to their lead in front of their home fans is a matter of principle.
Brann is in a completely different situation: the Norwegian season hasn't even begun, and the team is only playing friendlies. The visitors' form is seriously questionable. The Norwegians failed to score against Bologna in the first leg, and it will be even more difficult to do so away from home.
Bologna will control the match, playing to the scoreline and not forcing the issue. The quality of the Italian team, the support from the crowd, and the opponent's lack of match practice are all significant factors. Even if the hosts allow themselves to economize, their level is sufficient for another victory.
