Live updates on transfer rumours.
TransferFeed valuation based on market analysis.
Recent reports from February 2026 suggest Arsenal may be willing to spend over €70 million, while a gentleman's agreement was also reported for Sporting to analyze offers between €40-€50 million. Throughout 2025, numerous reports indicated a potential deal could be struck between €50 million and €60 million, with Manchester United reportedly preparing a €60 million bid in January 2025. Crystal Palace was widely reported to have agreed a €55 million fee in July 2025. Sporting's asking price was consistently cited around €60 million during 2025. A release clause of €80 million is consistently mentioned in his contract, which was renewed in January 2026. His Transfermarkt value was noted at €45 million in late 2025.
Our valuation is driven by numerous consistent reports from 2025 and 2026 establishing a clear market price. Sporting CP's asking price is repeatedly cited as €60 million, and a deal with Crystal Palace was reportedly agreed at €55 million in July 2025. The intense and persistent interest from multiple top-tier Premier League clubs, including Arsenal, Chelsea, and Manchester United, supports a valuation for Ousmane Diomande at the higher end of this reported range.
