According to Sky, Union Berlin expressed loose interest in German striker Marvin Pieringer, 26, as a potential contingency for the departure of Ilyas Ansah, who is being pursued by Premier League newcomers Hull City. However, the club's approach for the 1. FC Heidenheim striker was apparently too late, as he is now set to join his former club SC Paderborn. Pieringer joined Heidenheim in July 2023 and has a contract that runs until 2027. According to Transfermarkt, he has a current market value of €3.0 million. He moved to Heidenheim from Schalke in 2023 for a fee of €1.8 million.
