Chelsea midfielder Hakim Ziyech is warming to the option of a January move to Borussia Dortmund.

BILD reports Dortmund are looking to bring in Ziyech as they seek January reinforcements.

Contact has supposedly taken place between Dortmund and Ziyech's representatives, and the player is said to be keen on a move to Germany.

A loan move is the likeliest scenario because Chelsea do not want to lose Ziyech permanently.

However, Ziyech appears ready to start a new challenge, with his Chelsea career not going to plan.
