Tylel Tati, an 18-year-old French and Senegalese centre-back, is under contract with Nantes until 2028, and his contract is set to be extended to 2030. When he was 17, Tati signed his first three-year professional contract with Nantes, which included an option for two more years after he reached majority. In Ligue 1 this season, he has made 19 appearances and has also received three caps for the France U18 team. According to Transfermarkt, his current market value is €12.00m. Several clubs have been linked with Tati, such as Chelsea, Strasbourg, RB Leipzig, and FC Bayern München. In February 2026, a verbal offer of €30 million from Chelsea was reportedly rejected. At that time, Nantes was said to be unwilling to enter discussions for less than a range of €40 to €50 million. By March 2026, reports indicated the club expected a transfer fee of at least €50 million.
