Besiktas have sent a delegation to London to begin talks with West Ham striker Javier Hernandez, according to reports to Turkey.
The Mexican has struggled to perform since joining the Hammers in the summer, and manager David Moyes could decide to cash in before the end of the month.
Manchester United have been linked with a sensational return for Hernandez, who left Old Trafford for the Bundesliga back in 2015.
Hernandez enjoyed a return to form with German outfit Bayer Leverkusen before joining West Ham in a £16million deal in July, but the move hasn't quite worked out for the 29-year-old.
