Martin Delavallée

Martin Delavallée grew up in the youth academy of Royal Excel Mouscron, signing his first professional contract there in June 2021 and making his league debut the following April in the Challenger Pro League. His time at Mouscron ended abruptly when the club went bankrupt that June, and Delavallée moved to Charleroi on a free transfer, a deal announced days later and taking effect at the start of the following season.

He signed an initial one-year contract with an option for a further season, which Charleroi exercised, and he has since extended his stay until 2027. For his first two seasons at the club, he established himself as Charleroi's starting goalkeeper during the second half of the 2024–25 campaign.

At international level, Delavallée has represented Belgium at youth level, with one cap for the under-18s, on debut against Czechia, and one for the under-21s. He was named in the squad for Belgium's qualifying campaign for the 2027 UEFA European Under-21 Championship. He has not featured for the senior national side.

Delavallée's career so far has come without major trophies. He did pick up some recognition away from the pitch, receiving an Honourable Mention in EA Sports FC 26's Team of the Year, with a special in-game card rated 72.
