Free agent and former Croatian international centre-back Matej Mitrović is scheduled to join Osijek on trial as the club seeks to strengthen its defense. The defender is expected to join the squad this week, and coach Federico Bessone will then evaluate him before a final decision is made regarding a contract. Mitrović's most recent club in Croatian football was Rijeka during the 2023/24 season, which was followed by a period at Al Ahli in Qatar.
