Mergim Berisha is transferring from TSG Hoffenheim to 1. FC Kaiserslautern. It is reported that the Bundesliga club is waiving a transfer fee. The club is also said to have secured a very high sell-on clause. At TSG, Berisha was not selected for matches, was no longer part of the professional squad, and was one of the top earners at the club. The "Red Devils" are responding to the injury of Ivan Prtajin, who tore his Achilles tendon in the match against SV Elversberg on Saturday. FCK sporting director Marcel Klos stated that they had been considering Mërgim for some time.

According to 'Sky', Mergim Berisha will join 1. FC Kaiserslautern from TSG Hoffenheim on a free transfer. Berisha's contract with TSG Hoffenheim was valid until 2027, but a contract termination enabled the transfer as TSG had already loaned out six players within Germany. TSG Hoffenheim will receive a resale percentage. According to 'kicker', Berisha will sign a contract with 1. FC Kaiserslautern until 2027 that includes an option for an additional year.

According to Sky, 1. FC Kaiserslautern is signing German centre-forward Mërgim Berisha from TSG Hoffenheim. The signing is a reaction to an injury to Ivan Prtajin. The 27-year-old, two-time national player had fallen completely out of favor with the first team at Hoffenheim. The report states that no transfer fee is involved in the deal, but TSG will receive a very high resale percentage. Berisha joined TSG Hoffenheim in August 2023 for a reported fee of €14 million, and his current Transfermarkt market value is €2.50m.
