Leandro Rousseau was linked with Hertha BSC, but a transfer was not completed. There is still interest from Belgium and the Netherlands for Rousseau. Patro Eisden requires a fee between €1 million and €1.5 million for a club to sign him. Stijn Stijnen stated that Rousseau is not gone yet and the time pressure for candidate buyers is increasing.

According to Sacha Tavolieri, Hertha BSC is making efforts to sign 23-year-old Belgian forward Léandro Rousseau from Belgian second division club Patro Eisden. The forward is reportedly a high priority for the Berlin club and an offer is expected soon. Dutch top-flight club PEC Zwolle is also interested in Rousseau. He joined Patro Eisden on a free transfer from Olympique Charleroi last summer. In the 2025/2026 Challenger Pro League season, he scored 17 goals and provided 1 assist in 31 appearances. His contract with Patro Eisden runs until June 30, 2027, and his current market value is €1.00m, according to Transfermarkt.
