Koni De Winter, born on 12 June 2002 (age 23), is a Belgian central defender with AC Milan. An imposing 6ft 3in (1.91m), he wears the No 5 shirt and is valued at around £19.5m by Transfermarkt.
His career has been shaped most clearly by Genoa, where he made 54 league appearances across two seasons and scored three times. The 2024-2025 campaign was his most productive, with three goals in 25 league matches, giving him a proper first-team platform rather than the usual polite promise attached to young centre-halves.
At AC Milan in 2025-2026, De Winter has remained a regular presence. He has made 26 Serie A appearances, scoring once, along with two Coppa Italia outings and one in the Supercoppa, taking him to 29 appearances and one goal in all competitions.
De Winter is still a developing defender, but not an abstract prospect. Genoa gave him the substance of his senior career, and Milan is now testing how far that can be carried at a higher level.
