Umar Sako, a central defender from Rostov, is under consideration for a potential move to the French league. Brest has expressed interest in the 28-year-old Nigerien defender. Reports from RB Sport indicate that scouts from the French club have been attending Niger's national team matches to watch Sako's performance firsthand. Currently, Rostov has not yet received an official request for Umar, but Brest is actively investigating the possibility of signing the player. Sako has been with Rostov since January 2024, having initially joined from Bulgarian club Arda on loan, before being fully acquired by Rostov in the summer.
