Union Saint-Gilloise vs Marseille prediction 09.12.2025 | Champions League

Union Saint-Gilloise had a historic last season, winning the Belgian title for the first time since the 1934/35 season. An incredible 90-year wait. This season, the popular "Les Unionistes" are doing well in the domestic league, where they sit atop the table with 37 points from 17 matches. In the Champions League, Les Unionistes are in 25th place, but on level with four other teams with six points. However, their poor goal difference puts them at a disadvantage, meaning they would almost certainly lose out if it comes down to that tiebreaker. So, winning as many points as possible in the remaining three rounds is crucial.

After a 1:1 draw with Gent in the previous game, coach David Hubert spoke to the media. He said they lacked the final push, or at least a bit of luck, to turn the match in their favor. The coach said they created more than enough chances to win, but weren't clinical. When asked whether the inefficiency was due to fatigue, he firmly denied. 

Marseille have been one of the best teams in France for most of the previous seasons. Last year, they finished second, but not even remotely close to winning the title. This season, "Les Phocéens" opened the Ligue 1 season well. However, after winning one point in the past two games, they dropped to third place, five points away from the top spot. When it comes to their Champions League performance, Marseille won all their points at home, and it will be interesting to see whether they can finally win away from home.

After a 1:0 loss vs Lille in the previous game, coach Roberto De Zerbi spoke to the media. He said they played badly and deserved to lose. "We didn't string three passes together. We lost every second ball. Even with dribbling, we couldn't beat anyone. Defensively, we were never as aggressive as we usually are. We were passive from the first minute to the last," the coach acknowledged their poor performance.
