Ousseynou Niang, a 24-year-old Senegalese left midfielder, has left Union Saint-Gilloise to join Zulte Waregem. He has signed a two-season contract that includes an option for an additional two years. Niang, who arrived at Union from Riga in the summer of 2024, had gradually declined in the team's hierarchy and is moving to get more playing time. His last match for Union was a twenty-minute appearance against Zulte Waregem. Upon joining, Niang stated that he always had a good impression of his new club from previous encounters. He also mentioned that he had recently called a player named Diop, who spoke positively about Zulte Waregem, and expressed hope that his own qualities would quickly benefit the team. Niang has two caps for Senegal's U23 team and his current Transfermarkt market value is €6.00m.
