Former Freiburg goalkeeper Mark Flekken has strengthened the ranks of Brentford, the club from London confirmed.
He has signed a four-year contract worth £11m with the Premier League club.
He helped Freiburg to fifth place in the Bundesliga this season.
The 28-year-old Dutch goalkeeper has most likely been brought in as a replacement for first-choice goalkeeper David Reja, who is speculated to leave Brentford.
