Royale Union Saint-Gilloise proved in the group stage that this team should not be underestimated (by the way, Union Berlin played in the same group, one of the matches against which Royale Union Saint-Gilloise won).
Union Berlin, although the squad looks the favorite today, but the team is on a slight decline, and Royale Union Saint-Gilloise is scoring a lot right now.
Prediction: both teams to score. We recommend the “BTTS - Yes” bet, odds 2.23
