Union Saint-Gilloise news

Union SG head into their upcoming European match in decent domestic form and are top of the Belgian Pro League.

In Europe, their campaign has been a roller coaster. They started with a strong away win at PSV Eindhoven but then suffered heavy defeats against clubs like Newcastle United and Inter Milan. They did bounce back recently with an important 1–0 away win at Galatasaray.

Injuries: Mohammed Fuseini is out injured.

Tactically: they remain likely to field a back-three with wing-backs and a midfield-heavy shape—their setup against Gent was a 3–4–1–2, showing their standard configuration. So ahead of their match the challenge will be to translate that domestic form into European stability.

Predicted lineup: Scherpen; Skyes, Burgess, Mac Allister; Niang, de Perre, Zorgane, Khalaili; Ait El Hadj; Davide, Florucz.

Olympique de Marseille news

Marseille arrive at this match under pressure, both from their European situation and injury issues.

On the competitive front, OM’s season has been inconsistent. Their domestic results have fluctuated recently, which adds pressure. In Europe, they remain in the battle for qualification and the upcoming match against Union SG is crucial for their hopes to progress from the league phase.

Injuries: Amine Gouiri, Facundo Medina and Hamed Traoré are all out injured.

Tactically: Given their injuries and form, maintaining defensive discipline and making the most of their attacking chances will be vital. OM must manage their limited resources carefully to navigate domestic and European fronts in the coming weeks.

Predicted lineup: Rulli; Emerson, Balerdi, Pavard, Weah; Vermeeren, Hojbjerg, Kondogbia; Paixao, Aubameyang, Greenwood.
