Jorthy Mokio is a Belgian centre back and defensive midfielder whose rapid rise has attracted wide attention on and off the pitch, and whose early milestones are already tracked by collectors and platforms such as Walkouts. Born and raised through the Belgian youth system, Mokio combines composure in possession with physical presence and reading of the game, qualities that have underpinned a string of record making appearances for club and country.
Mokio began his football education at KFC Merelbeke before moving to the academy of K.A.A. Gent in 2021. He first entered international youth competition when he made his UEFA Youth League debut against Basel on 4 October 2023, a match that made him the youngest Gent player to appear in the tournament. After progressing through the youth ranks, he became eligible for senior football on his sixteenth birthday and was handed his senior debut for Gent in the Belgian Pro League on 29 March 2024, starting in a 5-1 victory over Standard Liège. He made four first team appearances before the summer transfer window.
On 24 June 2024, Mokio signed for Dutch club Ajax on a free transfer. He began with Jong Ajax and made his Eerste Divisie debut against Jong PSV on 12 August 2024. Mokio established himself as a regular for the reserves, scoring twice in the first half of the season and alternating between centre back and defensive midfield roles. He reached the Ajax first team later that month, coming on as a substitute in the UEFA Europa League play off round against Jagiellonia Białystok on 29 August 2024, and in doing so became the youngest non Dutch player to appear for the club.
His integration into Ajax's senior side continued in early 2025. Mokio made his Eredivisie first team start at left back against Fortuna Sittard on 9 February 2025, becoming the club's second youngest ever player to start a league match. Four days later he was handed his first European start in the Europa League knockout round play offs against Union Saint-Gilloise and scored a volleyed goal in a 2-0 win on 13 February 2025, becoming the youngest scorer in a UEFA Europa League knockout stage match.
Internationally Mokio has represented Belgium across youth levels, and he is of Congolese descent. He progressed through Belgium's U15, U16 and U17 teams before making his U21 debut in September 2024 against Kazakhstan, a match in which he scored. Mokio made his senior debut for the Belgium national team in the UEFA Nations League play off against Ukraine on 20 March 2025, aged 17 years and 19 days, one of the youngest to represent his country.
For collectors, Mokio's early and clearly dated milestones provide strong provenance for signed shirts, authenticated autographs and match referenced memorabilia. Certified pieces that reference specific moments such as his Ajax debut on 29 August 2024, his Eredivisie start on 9 February 2025, or his Europa League knockout goal on 13 February 2025 help establish clear provenance tied to verifiable match day appearances and landmark goals. Authentic autograph items, match worn shirts, and documented memorabilia are the forms of merchandise most commonly sought by serious collectors.
At every stage Mokio has combined technical ability with maturity beyond his years, and his emerging list of first team and international appearances maps directly to items of collectible significance. As his career progresses his recorded achievements will remain central to provenance records and to the narrative around authenticated collectibles. For those collecting today, Walkouts offers a way to discover and verify signed shirts and other authenticated merchandise linked to these early milestones.
