Union SG vs Marseille prediction: Les Olympiens to triumph

Key stats

  • Union SG have lost won once in their last six games across all competitions (W3, D2).
  • The Belgian side haven’t scored more than twice in their last seven games.
  • Marseille have won two and lost three of their five UCL matches this term.
  • Les Olympiens have lost six of their last 10 competitive away games (W4).

Correct score prediction: Union SG 1-3 Marseille

Royale Union SG staged a matchweek four upset at Galatasaray’s Rams Park, beating the Lions by the narrowest of margins to earn their second UCL win. However, Union remain winless in two of their three games since then.

The reigning Belgian champions will meet their adversaries in Marseille, who enter this clash on the back of their first loss in five games. The Olympians beat Newcastle United 2-1 in last UCL matchday, and Robert de Zerbi will be keen to see his rise in the standings, as they currently occupy the 21st position.

Both sides tasted victories in their respective previous UCL matches but Marseille will be confident to claim maximum points thanks to their superior individual quality on the ball.
