Loaned from Sunderland at the start of the season, Jeremain Lens has been unable to make an impact at Besiktas.
The Sunderland loanee is currently down the pecking order, with Besiktas manager Senol Gunes favouring Ryan Babel and Ricardo Quaresma in recent weeks.
Lens’ slow start to the season has been highlighted in the Turkish media, and Gunes labelling him a ‘missing person’.
The Turkish newspaper say Lens is lazy and isn’t working hard enough. They claim Lens’ weight is a problem, and that the Dutchman has been instructed to lose some pounds by the Besiktas medical team.
With Sunderland’s continuing problems the possibility of a high earner returning to the club wouldn’t be an ideal situation, and the Championship side will be hoping he returns to the form he showed with Fenerbahce in the last campaign.
