West Ham United left-back Arthur Masuaku has left the club on a season-long loan to join Turkish side Besiktas.
The Democratic Republic of Congo international has moved to the Turkish Super Lig side in a deal for the duration of the campaign that includes an option to make the move a permanent one next summer.
Since moving to east London from Greek side Olympiakos six years ago, Masuaku has made 129 appearances for the club and scored twice in all competitions.

The exit comes despite Masuaku starting in the Hammers' final friendly of pre-season against French club Lens on Saturday evening in France. His move will see him play for a side managed by former West Bromwich Albion and Barnsley manager Valerien Ismael.
Masuaku's exit opens the door for a new versatile left sided player to come in. Football.London understands the club are interested in both Eintracht Frankfurt's Filip Kostic and Burnley's Maxwel Cornet, although it is likely that it would only be one of them that arrives if either did.
West Ham start their new campaign at home to Manchester City at the London Stadium on Sunday.
