Cherki had been linked with a move to Dortmund in the summer and now, journalist Santi Aouna, who works for Foot Mercato, has published leaked WhatsApp messages that have been sent by Textor, seemingly to an executive at a different club, in which he calls Cherki an "asshole". A later exchange shows Textor saying that he will tell Dortmund to "f*ck off" because of their lack of replies.
