FIFA have confirmed they've received a complaint from Loris Karius against his club Besiktas.

The German goalkeeper is on-loan at Besiktas this season from Liverpool, but reports had stated he had lodged a complaint with FIFA over allegations of four months of outstanding wages.

And a FIFA spokesman, contacted by the France-Presse agency, has confirmed the complaint was received - though refused to go further.

Karius, 25, is on a two-season loan at Besiktas with the option to sign permanently.
