Royal Union SG – Marseille: Match preview

Union SG enter the decisive round with six points from five Champions League matches and remain firmly in the race for the knockout stage. They opened the campaign by beating PSV 3–1, but then suffered three consecutive defeats, conceding 11 goals and scoring only once across those games. In their previous European outing, the Belgians edged Galatasaray 1–0. Domestically, Union SG top the league table with 37 points after 17 rounds, holding a four-point advantage over second place.

Marseille have collected 29 points from their last 15 Ligue 1 fixtures and currently sit third, still pushing for the top and trailing first place by five points. Their Champions League run began with a 1–2 loss to Real Madrid, followed by a dominant 4–0 win over Ajax and another setback. First a 1–2 defeat to Sporting, then a 0–1 loss to Atalanta. Only in the fifth round did they manage a comeback, overturning a 0–1 deficit to beat Newcastle 2–1 at home. They sit on six points with a goal difference of 8–6, placing them 21st in the Champions League standings.

Probable lineups

  • Union SG: Scherpen; Mac Allister, Burgess, Sykes; Boufal, Zorgane, Van de Perre, Niang; Ait El Hadj; Rodriguez, Akinpelu
  • Marseille: Rulli; Pavard, Balerdi, Palmieri; Weah, O’Riley, Hojbjerg, Gomes, Paixao; Aubameyang, Greenwood

Prediction

A high-stakes, demanding match awaits both sides as they battle for a playoff spot. Union SG are a strong home team and should have their chances. I expect the Belgians to avoid defeat in front of their own supporters.
