Rasmus Carstensen has joined Lech Poznań on a loan from FC Köln, which is valid until June 30, 2025. He underwent a detailed medical examination in Poland, and it was successful, enabling the transaction to be finalized. Lech Poznań attempted to include a buyout clause valued at two million euros, but FC Köln did not consent to it. Carstensen is anticipated to enhance the competition on the right side of the defense, although he is also capable of playing on the left side. The sports director, Tomasz Rząsa, conveyed his excitement about Carstensen's arrival and expressed hope that he will contribute to the fight for the Polish championship.
