Kerim Frei could be set for a return to Fulham, according to reports in Turkey.
Turkish newspaper Sabah claims the 22-year-old winger is on the radar of the Championship club.
He left Craven Cottage for Besiktas in 2013, but has fallen out of favour at the Turkish club.
The winger has only played twice in the league this season and has not featured since September.
And manager Senol Gunes is reportedly willing to let the Turkey international return to Craven Cottage in January.
Frei was at Fulham between 2010 and 2013, making 33 appearances in all competitions, including 23 in the Premier League.
He scored once for the Whites, against Odense in the Europa League.
The 22-year-old has played 99 times for Besiktas, scoring nine times.
He made his international debut in 2012 and has gone on to make five appearances for Turkey.
Fulham manager Slavisa Jokanovic admitted earlier this month the Whites are searching for targets to improve their squad as they mount promotion push.
He said: "We're checking the market. The board and the owner might be looking. I'm always looking."
