Herba Guirassy is regarded as one of the most probable departures from his club. For several months, Spanish clubs, with Real Sociedad being a notable example, have been monitoring his progress.

FC Nantes recently rejected a paid loan with a purchase option from Real Sociedad for their 19-year-old French and Guinean winger, Herba Guirassy. The Basque club sought to sign the player, but Nantes, who are competing to remain in Ligue 1, rejected the offer. The Canaries prefer to retain the player, whose contract runs until 2028, viewing him as an integral part of their current sporting project and essential to their ambitions. It has been reported that Guirassy's performances have attracted attention from several European clubs in recent months. His current Transfermarkt market value is €6.00m. This season in Ligue 1, Guirassy has made 15 appearances, scoring 2 goals and providing 1 assist.
