Massiré Sylla, born on 7 January 2005 (age 21), is a Senegalese central defender with the frame for the job: a commanding 6ft 5in (1.96m). He wears number 29 for Union Saint-Gilloise.
His career to this point is still shaped most clearly by Lyn. Across two seasons there, he made 27 league appearances, giving him the foundation of regular senior football rather than the usual thin line of youth-team promise and guesswork.
At Union Saint-Gilloise, Sylla has remained involved in 2026-27. He has made 10 league appearances and scored once, alongside outings in Champions League qualifying, the Super Cup, the Europa League and the Pro League play-offs. Across all competitions for the club, he has 20 appearances and one goal.
Sylla is still a developing defender, but his career already has a fairly clear shape: senior grounding at Lyn, followed by a regular first-team role at Union Saint-Gilloise.
