Kehl said after Dortmund's Club World Cup exit: "Carney’s loan ends today. That was what we agreed with Chelsea. Now, let’s see. We will definitely have some more discussions in the next few days about his situation. I think it was a good move from Carney to join us.
"Now let's see how we manage everything. It won't be easy, but for sure we will try to keep him because he's a very good player. This topic is something for the future, and right now I don’t know what will happen.
"It's always easier to loan a player than to buy one, especially within Carney’s [price] range. But let's see," he continued. "We are not that far advanced [in talks] at the moment, but I can tell you that we are pretty close to the player, and he loves Dortmund, so this is quite good. Everything else will be decided between Chelsea and us. That won't be tomorrow. That won't be on Tuesday. I think it will take some more days."
