Union Saint-Gilloise are an old Belgian name with a very modern profile. Founded in 1897 and based at Het Joseph Marienstadion, they sit first in the Pro League in the 2026-27 season, carrying a 30-man squad with an average age of 24.
Their domestic form is carrying real force. The recent league run shows five wins and a draw, including a 1-0 win over Genk, a 2-1 away win at Beveren, and heavier work in 5-2 and 5-0 home victories over Cercle Brugge and Lommel. At home, they are averaging 2.5 goals scored and just 0.5 conceded per match; away, the attacking figure rises to three goals per game.
Raul Florucz has been the main scorer with nine goals, while Guilherme Smith, Relebohile Mofokeng and Besfort Zeneli have each added five. The spread matters: this is not a side leaning on one source of damage, and their numbers point to a team comfortable forcing games open while still keeping a tight base.
Their season has also taken in the Beker van België, the Super Cup final, Champions League qualifying, Europa League qualifying and the Europa League league phase. For Celtic supporters, Union Saint-Gilloise look like a well-balanced Belgian side in strong domestic form, with enough pace in attack and discipline behind it to merit proper attention.
