Leeds United are making a bold move in the summer transfer window, targeting Sporting Lisbon’s defensive star Ousmane Diomande despite the Portuguese club’s firm stance that he is not for sale. According to reports from Portuguese outlet A Bola, the Championship side has already opened direct communication with the player’s representatives.
The 22-year-old Ivorian center-back has been a key figure in Sporting’s recent dominance, helping the club secure back-to-back Liga Portugal titles. His rise has not gone unnoticed, with Premier League clubs circling for the past two transfer windows.
A Wanted Man for Years
Diomande arrived in Lisbon in January 2023 from Danish side FC Midtjylland for just €7.5 million. Since then, his value has skyrocketed. Crystal Palace showed interest last summer but balked at the asking price. The previous year, Liverpool, Newcastle United, and Manchester United all considered making a move.
The 2025-26 season was interrupted by injury for Diomande, who managed 17 league appearances and one assist. Still, clubs see him as a long-term investment with massive upside.
Leeds, freshly promoted and looking to strengthen their defensive line at Elland Road, are not backing down despite the obstacles. Sporting Lisbon, according to reports, wants to keep Diomande for at least another year and is expected to resist any offer.
The Numbers Behind the Move
Leeds is reportedly prepared to offer €40 million up front, with an additional €10 million in performance-related add-ons — bringing the total package to €50 million. For context, Diomande’s current release clause is set at €80 million, so Leeds is betting that a substantial cash offer could change Sporting’s mind.
The next step, according to A Bola, could be a formal proposal submitted directly to Sporting’s board. The Yorkshire club is aware that they will need to turn heads with the financial package, as Sporting has shown little appetite for negotiations.
Whether Sporting budges or not, Leeds has already signaled to Diomande’s camp that they are serious. The player’s camp has been approached, and conversations are underway. For now, the ball sits squarely in Sporting’s court — but Leeds is making sure the noise is loud enough to be heard clearly in Lisbon.
