West Ham defender Arthur Masuaku has failed to convince Besiktas management.
Masuaku joined the Turks on a season-long loan over the summer.
However, the defender hasn't done enough to convince Besiktas to trigger his permanent option.
Instead, Besiktas plan to send Masuaku back to West Ham in January.
The Eagles have similar plans for on-loan Everton midfielder Dele Alli.
