Dennis Jastrzembski is currently undergoing sports tests with Arka Gdynia, a club in the Polish Ekstraklasa. According to Tomasz Włodarczyk from Meczyki.pl, the final decision regarding his move to the club is expected to be made on Saturday. Although Jastrzembski has a contract with Fortuna Düsseldorf until June 30, 2026, the club has reportedly allowed him to leave, as they do not have future plans for him, particularly following a serious back injury that limited his appearances. Jastrzembski, originally from Rendsburg, might return to the Polish top flight if he joins Arka, after his previous tenure at Śląsk Wrocław where he played 47 matches, scored three goals, and provided three assists. His last game was in September of the previous year, and it appeared challenging for him to find a new club until Arka Gdynia showed interest, potentially offering him an opportunity to revive his career in Poland's top tier.
