Kacper Kostorz has attracted interest from 1. FC Magdeburg. He is currently under contract with Pogoń Szczecin until June 30, 2026. The interest from Magdeburg is linked to the departure of Martijn Kaars to FC St. Pauli. Kostorz returned to Pogoń Szczecin this summer after being loaned out to various clubs, including Korona Kielce, FC Den Bosch, and NAC Breda.

Kacper Kostorz, after returning from a loan spell at NAC Breda where he scored three goals in 24 appearances, is set to return to Szczecin to showcase his skills to coach Robert Kolendowicz. He was not included in the training squad for Pogoń Szczecin's camp in Opalenica, which had suggested he might not have a future at the club. However, he will now present his abilities to the coach, who will then decide on his future at the club.
