Chelsea are set to put a choice of five players up for sale to fund move for Sevilla’s Jules Kounde.
The 22-year-old Frenchman has a £68m buyout clause which could put off potential suitors.
The Blues could try and agree a lower fee as Sevilla would not want to stand in their players way if he wants to leave.
AS reports that Tuchel would also be keen to some of his stars in a swap deal for the Frenchman.
Playmaker Ziyech has already been mentioned, while Kepa Arrizabalaga is another who will be offered.
Another option mentioned is Tammy Abraham, who has found minutes hard to come by following Tuchel’s arrival.
Tiemoue Bakayoko, on loan at AC Milan, and Michy Batshuayi, who has spent the season with Crystal Palace, may also be available.
In Spain, Chelsea are now regarded as showing the most concrete interest in closing a deal for Kounde.
