In a decisive move during the 2025 summer transfer window, AC Milan has finalized the transfer of promising Belgian defender Koni De Winter from Genoa. The agreement sees Milan paying a €20 million fee, with additional bonuses potentially raising the total to around €25 million.
Deal Highlights
- The €20M base fee is supplemented by performance-related add-ons, bringing the total deal closer to €25M.
- As part of the agreement, Juventus will receive a resale percentage — initially set at 25%, later adjusted due to playing time clauses.
Why De Winter?
Koni De Winter (born June 12, 2002, in Antwerp, Belgium) is a versatile defender with the ability to operate as a centre-back or a full-back, providing tactical flexibility. He emerged from Juventus’ youth ranks before proving himself at Empoli and, most notably, Genoa, where he made significant contributions across the past two seasons.
Head coach Massimiliano Allegri is familiar with De Winter from his Juventus days and reportedly endorsed the move.
Context of the Deal
De Winter arrives at Milan as a direct replacement for Malick Thiaw, who is on the verge of joining Newcastle United in a separate deal worth approximately €40 million including bonuses. AC Milan had also faced competition from Inter and other clubs, but ultimately secured the signing for a fee significantly lower than some of their alternatives, such as Giovanni Leoni (whose asking price was estimated at €40M).

What Comes Next
De Winter is expected to undergo medical tests early in the coming week before finalizing his long-term contract with AC Milan. His move is seen as a strategic, financially astute investment—blending value, versatility, and Serie A experience as the Rossoneri prepare for the new season.
