Billy Koumetio is a French central defender, born on 14 November 2002 (age 23). An imposing 6ft 5in (1.95m), he is now with Charlton Athletic, where he wears squad number 12. His market value is around £340,000, according to Transfermarkt.
His early senior career included a brief 2022-23 spell with Young Violets, where he made four league appearances. The more substantial part of his career, though, came at Dundee. Across two seasons there, Koumetio made 40 league appearances, giving him the kind of regular football that has done most to shape his profile so far.
For a player still in the developing category, Dundee remains the clear reference point: not a footnote, not a passing loan, but the spell where he was properly used. That matters, particularly for a young centre-half whose game is judged as much on repetition and reliability as on promise.
By 2026-27, Koumetio was at Charlton Athletic and had made four appearances across the Championship and League Cup. His career to this point is a straightforward one: limited early senior football, a defining run at Dundee, and a move into the English Championship with Charlton.
