Borussia Dortmund has ruled out letting Neven Subotic leave on a winter transfer.

Subotic, who has only played four matches in all competitions this season, has been linked with Jurgen Klopp's Liverpool.

Thomas Tuchel said: "From a coach's point of view, I can say that we need Subotic. He's an integral part of the team. If it comes down to me, but it's not always like that, there is no reason to consider a switch."
