Chelsea are reportedly refusing to budge on their €30m (£26.98m) valuation of midfielder Tiemoue Bakayoko.
With the player having spent the last two seasons out on loan, the Blues are happy to cash in on the France international as soon as possible.
AC Milan, who signed Bakayoko on loan for the 2018-19 campaign, are keen to negotiate another deal for the 26-year-old, potentially on loan with an option to buy.
However, according to Gazzetta dello Sport, Chelsea are playing hardball over an asking price, insisting that they will not agree to a compromise.
Given their desire to sign targets for other position, the report suggests that Milan do not want to pay over €25m (£22.49m).
Bakayoko has two years remaining on his contract at Stamford Bridge.
