Lasse Flo

Lasse Flo's route to professional football ran entirely through one club. He joined the Vejle Boldklub academy in 2017 after starting out at Hedensted IF, and worked his way through the youth ranks until his senior debut in the 2022/2023 Danish 1st Division season. That campaign ended with the title and promotion to the Superliga, though Flo's own contribution was limited to a single league appearance as the squad around him secured the achievement.

His path to a regular starting role took another two seasons. Flo established himself as a first-choice right-back in the Superliga during 2024/2025 and continued in that role into 2025/2026, taking his tally to 47 appearances for Vejle's first team across his time at the club. Alongside his club progress, he was capped by Denmark at under-19 level, including appearances in qualifiers for the 2024 UEFA European Under-19 Championship, and played three friendlies for the under-20 side that year. He has not featured for the senior national team.

In July 2026, Vejle sold Flo to the Belgian club KVC Westerlo. The fee was reported at around €1.5 million including bonuses, with a base figure of roughly €1 million cited by some reports, and Flo signed a four-year contract with his new club. Westerlo introduced him to their supporters as a Danish right-back.
