Chelsea's Mohamed Salah and Nathan Ake could reportedly both join Besiktas on loan before the end of the transfer window.
The Turkish club's president Fikret Orman has confirmed that negotiations with the Blues have taken place, although he refused to confirm the identity of the two players.
"I was in England and held talks with Chelsea but it would be wrong to disclose who the negotiations were regarding," he told Best FM.
"The talks are ongoing, if I was to tell you who the transfer was regarding it could make the move more difficult."
Salah, who joined Chelsea from Basel last January, has made just 13 Premier League appearances for the club, while young defender Ake has had four outings in all competitions this term.
