Brentford have signed Sivsspor midfielder Yunus Emre Konak.
Konak will initially be registered with the B team. The Turkey U21 international joins 4m.
Brentford director of football Phil Giles said: Yunus is an exciting young player and we are very happy to have managed to bring him to Brentford.
He's a player that likes to be aggressive, close players down, win tackles, and get the ball back for his team. He has a lot of development potential still, especially on the offensive side of the game, and we look forward to working with him on all aspects of his game.
Our recruitment team did a fantastic job to enable us to move quickly and secure his signature. We look forward to working with Yunus and, hopefully, he can progress into the first team in due course."
