Borussia Dortmund chief Hans Joachim Watzke says they won't panic if Liverpool make a January attempt for their players.

Reds boss Jurgen Klopp has confirmed this week there is no agreement preventing him from signing his former BVB players.

Mats Hummels, Marco Reus and Pierre-Emerick Aubameyang have been linked with Anfield this season.

"First I want to clarify that the relations with Jurgen are excellent," Watzke told Die Welt.

"There would be no problems if he was interested in one of our players, of course, he should first talk with us."
