Besiktas chairman Fikret Orman was in London on the weekend.

Orman was at Stamford Bridge to see Chelsea defeat Newcastle United and discuss a potential loan deal for Nathan Ake and Mohamed Salah.

Besiktas and Chelsea struck a partnership agreement before Christmas.

"That's true, but I'm not able to say much more about it at this stage," said Orman on Best FM. "That can harm the negotiations."

Chelsea do not wish to sell Ake, but are happy for him to play away on-loan for the remainder of the season.
