"Mark Flekken has a great wealth of ability that a goalkeeper needs in top-level football today. He has great reflexes, dominates his area well and has enormous reach with his height of 1.95 metres. Mark has an impressive physical presence and in terms of football he was one of the best keepers in the Premier League over the past two years," said Bayer 04 sporting managing director Simon Rolfes. "He knows the Bundesliga from his successful time at Freiburg. The years in England and his role in the Netherlands team have brought Mark a great amount of international experience on top of that. We are very well placed in the goalkeeping position for the team in the coming years," declared Rolfes.
For the Oranje keeper with eight caps, the move to Bayer 04 is "the next and special step in my career. Many games against absolutely world-class players in England have raised the level of my game," said Flekken. "I'm very happy to be able to dedicate my qualities now to a top German club with big national and European targets. I love the Bundesliga and I'm obviously also looking forward to playing for the Werkself in the Champions League."

Flekken returns from England as a seasoned player to Germany where he was a U17 player for Alemannia Aachen. After playing for Greuther Fürth and MSV Duisburg, he signed for SC Freiburg in 2018 where he made his breakthrough. He played 96 games for the Freiburg side and became one of the top goalkeepers in the league, which brought Flekken to the attention of foreign clubs. The model athlete made 74 Premier League appearances for Brentford over two seasons.
