Several Bundesliga clubs are interested in 1. FC Nürnberg's 23-year-old defender, Fabio Gruber. According to a report by 'Bild', 1. FSV Mainz 05 is currently the most likely destination. The report also states that Borussia Mönchengladbach and FC Augsburg are closely monitoring the Peruvian international's progress. Augsburg is familiar with Gruber from his time in their youth academy. Although his contract with Nürnberg runs until at least 2028, a summer transfer is considered increasingly probable. It is reportedly believed within the club that he will be difficult to retain. 'Bild' also reports that Gruber's contract does not include a release clause. Gruber has 3 caps for Peru, and his current market value on Transfermarkt is €2.00m.
