Siebe Roland Wylin

He joined the club's academy at the age of eight and stayed through the U16 age group, before switching to KV Oostende's youth ranks in 2019. It was at Oostende that he made his senior breakthrough, debuting on 2 October 2021 and going on to make around 37 appearances and score one goal across the Belgian Pro League and Challenger Pro League by 2024.

In July 2024, Wylin returned to the Club Brugge organisation on a free transfer, though not to the first team itself — he was assigned to the reserve side, Club NXT, where he made close to 49 appearances and scored four goals. A first-team debut for Club Brugge KV never materialised. On 10 July 2026, he moved on again, joining Eredivisie side Fortuna Sittard on a free transfer and signing a contract until 30 June 2028.

Wylin operates mainly at right-back, though he has also been used in midfield. At international level, he was capped twice by Belgium's U20 side in 2022. He has been sidelined by injury for a combined 113 days over the course of his career, and has yet to add a major team title or individual award to his record.
