Ousmane Diomande

Recent reports from June 2026 indicate Leeds United are preparing offers totaling between €45 million and €50 million, with Sporting CP's minimum asking price reportedly set at €50 million. Throughout 2025 and 2026, a negotiable price between €40 million and €60 million has been consistently mentioned by various outlets in connection with clubs like Chelsea, Arsenal, Manchester United, and Bayern Munich. A strong historical data point is the widely reported €55 million fee that Crystal Palace had allegedly prepared or agreed upon in the summer of 2025. While a release clause is consistently reported at €80 million, most rumours suggest Sporting is willing to negotiate for a lower fee.

Our valuation for Ousmane Diomande is driven by a high volume of consistent reporting. The range is anchored by recent (June 2026) rumours of Leeds United preparing offers totaling €45-€50 million and Sporting CP's minimum asking price of €50 million. The estimate of €55 million is strongly supported by multiple reports of Crystal Palace having a deal agreed at that price point in summer 2025, a figure that remains credible given the sustained interest from numerous top-tier European clubs.
