Tylel Tati was expected to leave FC Nantes during this summer transfer window and was considered in the spring as one of the most likely players to be transferred to help the club financially. Several clubs were interested in Tati, and his value on the transfer market was estimated to be between 20 and 25 million euros. According to Ouest-France, FC Nantes is now considering keeping Tylel Tati for another season in the absence of a satisfactory offer. It is now a possibility that Tati will stay at Nantes, but a departure cannot be completely ruled out before the end of the transfer window.

According to L'Équipe, Nantes is considering a potential sale of Tylel Tati. A sale could permit the club to offset a portion of the losses in the case of relegation to Ligue 2.

FC Nantes plans to activate an option in Tylel Tati's contract to extend it until June 2030, according to L'Equipe. Tati is currently valued at more than 25 million euros.

Olympique de Marseille is targeting Tylel Tati for the next summer transfer window. The French-Senegalese central defender from FC Nantes is closely followed by Marseille's scouts after an impressive season, in which he has made 19 appearances in Ligue 1. Marseille is relying on an ambitious sporting project and a promise of playing time to attract the 18-year-old player. His contract with Nantes runs until June 2028, and the France U18 international has also attracted interest from several other clubs, including Chelsea, RB Leipzig and Bayern Munich. FC Nantes does not intend to sell Tylel Tati without a significant offer. The situation could accelerate in the coming weeks as the transfer window approaches. Tylel Tati is currently valued at 12 million euros and has an annual income of 730,000 euros.
