Diogo Costa

Recent reports from May/June 2026 state that Porto will only sell for the player's €60 million release clause amid interest from Paris Saint-Germain. In May 2026, Real Madrid was reportedly preparing a €50 million bid. In April 2026, Liverpool's interest was linked to a release clause understood to be £52 million (approx. €61M). Juventus reportedly valued the player between €45-50 million in March 2026. In 2025, numerous reports emerged: Aston Villa was said to be ready with a €50 million move; Manchester United was linked with fees ranging from €50 million plus add-ons to €60 million; and Manchester City reportedly had a €40 million offer rejected before preparing a bid closer to €60 million. Earlier reports frequently cited a higher release clause of €75 million.

Our valuation for Diogo Costa is driven by consistent reports of a release clause, which the most recent rumours from May/June 2026 place at €60 million. This figure represents the upper bound of our range. The lower bound is informed by multiple reports of interest and valuations from top clubs, including a planned €50 million bid from Real Madrid and a €45-50 million valuation from Juventus. Given Porto's firm negotiating stance and the player's long-term contract, we estimate a final fee will likely land in the upper half of this range.
