Besiktas have confirmed the termination of Wout Weghorst's spell at the club ahead of an expected move to Manchester United.
The Netherlands international has spent the first half of the season on loan in Turkey from Championship leaders Burnley but is poised to complete a return to England.
United have been on the hunt for a striker since Cristiano Ronaldo's departure ahead of the World Cup, and Weghorst emerged as the leading candidate fill the void at Old Trafford.
Weghorst's switch to United now appears all but done following Besiktas' confirmation on Friday that he has left the club.
"The temporary transfer agreement with our professional football player Wout Weghorst and his club has been terminated by mutual agreement with the player and his club," a statement said.
"Due to the early termination of the contract by Burnley, a termination fee of €2.8 million [£2.5m] will be paid to our club."
Earlier on Friday, Ten Hag confirmed Weghorst would not be signed in time to feature in Saturday's Premier League clash with Manchester City but outlined his desire for a deal to be completed swiftly.
