Diogo Costa

Recent reports from September 2025 indicate Aston Villa was prepared to pay €50 million, while Galatasaray had offers of €20 million (August 2025) and €25 million (September 2025) decisively rejected. Porto has consistently pointed to the player's €75 million release clause, though multiple reports throughout 2025 suggest a negotiated fee is possible. Manchester City reportedly had a €40 million offer rejected in April 2025 but was preparing bids around €60 million. Manchester United has been linked with fees ranging from €45 million to €60 million. Chelsea's interest in October 2024 was associated with a potential €70 million fee. Transfermarkt's valuation is frequently cited at €40 million.

Our valuation is driven by the consistently reported €75 million release clause for Diogo Costa, which sets a clear upper boundary. However, numerous reports concerning top Premier League clubs, particularly Manchester City and Manchester United, suggest Porto is willing to negotiate a sale for a figure closer to €60 million. The rejection of lower bids and the persistent high-level interest support a valuation significantly above the €40-50 million mark.
