Wilson Isidor

Recent reports from August 2026 suggest Sunderland have set an asking price of around £20 million (€24 million), which West Ham are reportedly willing to pay. His Transfermarkt value was cited at €18 million in mid-2026. Earlier, in January 2026, Sunderland's asking price was reportedly £25 million (approx. €30 million), which deterred interest, though Beşiktaş was reportedly prepared to offer €15 million. In September 2025, Sunderland's valuation was even higher at a reported £35 million (approx. €41 million). The player completed a transfer from Zenit St. Petersburg to Sunderland in February 2025 for a reported fee of €6.0 million.

Our valuation is driven by recent reports from August 2026 that West Ham are willing to meet Sunderland's asking price of around €24 million for Wilson Isidor. This figure represents a significant decrease from Sunderland's previous asking prices of up to €41 million, reflecting the player's reduced role. The lower end of our range is anchored by a reported €15 million offer from Beşiktaş in January 2026, establishing a credible floor for negotiations.
