St. Pauli has shown interest in bringing back Aljoscha Kemlein, who was on loan with the club during the latter half of the 2024 season and made 18 appearances. Union Berlin president Dirk Zingler mentioned that St. Pauli would need to present a concrete offer if they are genuinely interested in acquiring Kemlein. St. Pauli coach Alexander Blessin conveyed his interest in the player, while also expressing criticism towards Zingler for not selling Kemlein despite not giving him playing time.

A successful loan spell at St. Pauli has sparked interest in either a renewed loan or a permanent transfer. Aljoscha Kemlein has played in all 16 second-half season games. A permanent transfer could cost up to 2 million Euros.
