Leicester City are demanding world record money from Chelsea to sell Ben Chilwell.
The Mirror says Leicester have told Chelsea they value Chilwell, 23, even more highly than Harry Maguire.
England stopper Maguire, 27, became the world's most expensive defender last summer when he joined Manchester United for £80million from the Foxes.
Now Chelsea face having to top that fee to land Chilwell, who has 11 caps.
Leicester have sold a main asset each summer since winning the title following the exits of Maguire, Riyad Mahrez, Danny Drinkwater and N'Golo Kante.
Now Chilwell, who has been at Leicester since aged 12, is likely to be their next big sale.
The star is keen to quit for Chelsea where he sees his long-term future.
