The agent of Borussia Dortmund defender Neven Subotic insists no contact has been received from Manchester City.
Subotic's representative, Stephen Kelly, claims the City link is just speculation and admits any move this month is highly unlikely.
"I have not heard anything from anybody at Manchester City. It is just speculation," Kelly told skysports.com.
"I would be really surprised if Neven was to leave Dortmund in January.
"It would take something special for Dortmund to sell him as he is on a long-term contract there."
