Union Berlin has secured the services of Linus Güther, a 15-year-old youth national player, for their youth team. Meanwhile, Energie Cottbus asserts that they have a legally binding agreement with Güther until 2028, which was signed by his parents. The situation is likely to be settled in court. Despite the ongoing dispute, Güther was registered as a contract player for Union Berlin by the Berliner Football Association on July 1, 2025. Energie Cottbus is determined to pursue legal action to uphold their contract. Reports suggest that several clubs showed interest in Güther, who has demonstrated promising talent by scoring several goals for the U15 German national team. The controversy emerged as Energie Cottbus maintains that there is a signed agreement with Güther's parents, claiming it constitutes a clear legal contract. Cottbus's president, Sebastian Lemke, highlighted the legal clarity of their agreement, although it was noted that some signatures and dates were missing. Union Berlin, on the other hand, remains calm, having successfully registered Güther, and has not made any public comments on the ongoing legal proceedings. Cottbus has enlisted a prominent sports and labor lawyer to investigate their legal options, aiming to resolve the matter in court.
