Hakim Ziyech could yet be on the move from Chelsea in January.
BILD says Borussia Dortmund are eyeing the midfielder.
BVB coach Marco Rose wants a new attacker after Jadon Sancho's sale to Manchester United last summer - and Ziyech has emerged as a loan option for the Germans.
Ziyech has struggled to find regular minutes under manager Thomas Tuchel and could be open to a January exit.
The midfielder is in his second season with Chelsea after his move from Ajax.
