Schalke remain keen on Liverpool striker Divock Origi.
Origi has been made available by Liverpool for the January market and Schalke are among clubs keen.
Sky Deutschland says the feeling is mutual and Liverpool have offered Origi to S04 in order to discuss a deal for Ozan Kabak.
Origi would have to agree to a permanent departure for a swap to be negotiated with Kabak.
Along with Liverpool, AC Milan are also in talks with S04 for Kabak.
