Professional career

2022: Grand Slam qualifying debut

2023: First ITF title, First Challenger final

Debru reached his first Challenger quarterfinal in his first appearance of the year, at the Oeiras Indoors, Portugal. He reached another quarterfinal a month later at the Challenger La Manche in Cherbourg, defeating Kenny de Schepper before falling to British Jan Choinski. At his second French Open qualifying appearance he lost in the first round to Dominican Nick Hardt.

At the Open Sopra Steria de Lyon Debru made it to his first Challenger semifinal having defeated former Top 20 Benoit Paire, however he then lost to Alexander Ritschard.

In July 2023, Debru won his first ITF title in Gubbio, Italy by defeating Federico Arnaboldi in the final. He had reached the semifinals the year prior.

In August 2023, Debru reached his first final on the ATP Challenger Tour in Prague, as a qualifier, losing to Rudolf Molleker in the championship match.
