Bayer 04 LeverkusenFlekken has not yet won major trophies at the club level but was part of the Netherlands squad that reached the quarter-finals of the 2022 FIFA World Cup. He was also named SC Freiburg's Player of the Season for the 2021–22 campaign.
Mark Flekken is a Dutch professional goalkeeper who currently plays for Bayer 04 Leverkusen in the Bundesliga. He began his senior career in the Netherlands with RKC Waalwijk and later moved to SC Freiburg in Germany, where he established himself as a reliable shot-stopper. Flekken has also earned caps for the Netherlands national team, making his debut in 2022.
Flekken is known for his strong reflexes, commanding presence in the box, and excellent shot-stopping ability, particularly in one-on-one situations. He is comfortable with the ball at his feet and can distribute accurately, aiding his team's build-up play. However, his decision-making under pressure can occasionally be inconsistent, which is an area for improvement.
