Kicker reported that negotiations between Jeremiah St. Juste and 1. FC Union Berlin were in advanced stages. It was said that the club had reached an agreement with the defender and had submitted an offer of 2.5 million euros to his current club, Sporting Lissabon. The transfer fee could reportedly increase to three million euros with bonuses. St. Juste was said to prefer a return to the Bundesliga and would choose 1. FC Union over CA Osasuna, which was also interested in him. The potential transfer was dependent on Diogo Leite's possible departure from Union, as he was being courted by clubs such as Fiorentina, Bologna, and Girona. St. Juste's contract with Sporting was noted to run until June 2026, but the club was unlikely to block his transfer.

Although Sporting has yet to receive a formal proposal, the player's agent has informed them of the Bundesliga club's interest. St. Juste, who recently declined a transfer to Osasuna because of contract and tax issues, is willing to leave Sporting if his conditions are satisfied. Sporting had previously accepted a three million euro offer from the La Liga club, but the transfer did not materialize. Currently, St. Juste is the fifth-choice central defender at Sporting and has only one year remaining on his contract, increasing the likelihood of a transfer as Sporting is not expected to obstruct his departure. Transfermarkt estimates his market value to be €6 million.
