Turkish side Besiktas have exercised their right to sign Sunderland winger Jeremian Lens on a permanent basis.
The Dutch international has enjoyed loan spells at Fenerbahce and Besiktasin the last two years. Sunderland signed the 30-year-old from Dynamo Kyiv for £9m three years ago.
A statement on the club’s official website, www.bjy.com.tr, said: “As stated in our report dated 07.08.2017, the final purchase option for Jeremain Marciano Lens, loaned from Sunderland for the 2017-18 season, was used on 28.02.2018.”
Jeremian Lens joined the Black Cats on a four-year deal in an £8million move from Dynamo Kiev in July 2015 under then manager Dick Advocaat.
However, after a successful start to his career in England, his form dipped following Advocaat’s departure just three months later and his wage packet became a burden on an increasingly cash-strapped club.
