Beşiktaş is targeting Andreas Hanche-Olsen from Mainz to strengthen their defense. The Norwegian player, versatile in playing as a center-back, right-back, and left-back, has a contract with Mainz until 2026. Initial plans are to negotiate a transfer fee, but Beşiktaş is prepared to consider a loan option if an agreement can't be reached. Mainz is open to this idea to ensure regular playtime for the player as they participate in the Conference League. Currently, Transfermarkt estimates his market worth at 6.00 million euros.
