Union Berlin has won no match in this Champion League campaign, registering 2 draws and 3 losses. While Real Madrid have a perfect record so far, with 5 wins in 5 rounds. Moreover, the visitors have scored 13 goals and conceded just 5.
The results of this duel will not change the standing of any of these 2 teams, however, the match won't be a walk in the park. Both teams will be looking forward to claiming the last 3 points of the group stage.
Taking into consideration Los Blancos' capacity to win games on this big stage, I will back them to win.
