Janik Haberer is a 32-year-old German whose contract with Union runs until 2027. The midfielder's future at the club is uncertain as the new coach implements a more offensive playing style. He was considered a regular and dependable player under former manager Urs Fischer but has since had more difficulty securing a place in the team. A potential scenario is a move to Mainz, where Fischer is now in charge. It is reported that the manager is interested in bringing the player he previously favored to his new club, and it is also said that Fischer is interested in ex-Union player Sheraldo Becker. Haberer, who joined Union in July 2022, has a current market value of €2.00m according to Transfermarkt and has been capped 9 times for the Germany U21 team, scoring one goal.
