Klopp is adamant Dortmund players will not be off limits as he looks to bolster the Merseyside club's roster during the January transfer window.
"There is no agreement with Borussia Dortmund. I heard as well that there was one – these sort of things are always written at the time but, no it's not true," Klopp said.
"I have a good relationship with Borussia Dortmund and a good relationship with all the players there – there is nothing negative between us.
"So there could be a possibility – if we need a player then we could try. At this moment there is nothing to talk about.
"But there is no agreement that we can't do business with Dortmund. There's also no agreement that we can't sell players to Dortmund!"
The likes of Mats Hummels, Marco Reus and Ilkay Gundogan have all been loosely linked with the Reds in recent times.
