According to the newspaper 'Protathlitis', Lille's Tiago Santos is on Jose Luis Mendilibar's transfer list for the defensive flank of Olympiacos. The same report adds that although Santos is under contract with Lille until 2029, his relationship with the club's technical leadership is not optimal, which leaves open the possibility of his departure during the summer.

Olympiacos considers Tiago Santos an option for the position of second right-back after the acquisition of Pablo Maffeo. According to Kostas Nikolakopoulos, Olympiacos has already investigated the 24-year-old Portuguese player from Lille. Tiago Santos is represented by Jorge Mendes' agency, which has ongoing communication with Olympiacos.

Olympiacos is considering Tiago Santos, a 23-year-old Portuguese international from Lille, as a second option or an additional player for the right-back position. Santos is expected to depart the French club, which he joined from Estoril in July 2023 for a €6.5 million fee. According to indications from Lille, his departure is due to issues with the coaching staff, despite his contract being valid until 2029. In the 2025/2026 Ligue 1 season, Santos made 15 appearances and provided 1 assist. His current market value is listed by Transfermarkt as €10.00m.
