Joaquin Seys

Seys began playing football with Oostende, before joining the academy of Club Brugge in 2012. On 31 March 2022, Seys signed his first professional contract with Club Brugge until 2024, and was promoted to their reserves Club NXT where he became a starter. On 10 May 2023, he extended his contract with the club until 2026. With his Club NXT coach Nicky Hayen promoted to senior first-team head coach, Seys made his senior debut with Club Brugge at the 2024 Belgian Super Cup on 20 July 2024, starting in a 2–1 loss to Union Saint-Gilloise. Seys scored on his league debut a week later against KV Mechelen in a 1–1 draw, again as a starter. His selections continued into Club Brugge's UEFA Champions League campaign, making his debut in the competition against Borussia Dortmund, going off with the score 0–0 with 15 minutes to go. Without Seys, Club fell to a 3–0 home loss.

Seys is a youth international for Belgium, having played up to the Belgium U18s. Following a series of notable displays, including a 1–0 Champions League win over Aston Villa, Seys was called up to the Belgium senior squad by coach Domenico Tedesco for UEFA Nations League ties in November 2024 against Italy and Israel. In his next match after the announcement, Seys scored against Beerschot in a 2–2 draw only to go off with a leg injury that forced him to withdraw from the squad.
