Chelsea are prepared to sell Marcos Alonso next month.
Tuttosport says Chelsea are believed to have slapped a £30 million price-tag on Alonso.
The left-back, 28, is out of favour at Stamford Bridge, with Inter Milan interested in signing him.
They are keen to loan Alonso with an option to buy for £16 million - but Chelsea will demand no less than £25m.
Atletico Madrid have also been linked with the defender this past week.
