Union Berlin is interested in Jakob Golz from Rot-Weiss Essen as a backup goalkeeper for Frederik Rönnow. Golz has a release clause that allows him to leave for 150,000 Euros, but he prefers to stay in Essen. Union is also considering Elias Bethke from Energie Cottbus, who is reportedly higher on their list than Golz. The club's need for a new goalkeeper arises as Alexander Schwolow's contract will expire at the end of June. Additionally, Transfermarkt currently estimates his market worth at 325,000 euros.
