Chelsea have submitted a €35 million (£30.8m) offer for Inter Milan wing-back Denzel Dumfries, according to Italian media outlet La Repubblica via Metro.
Chelsea are keen on signing a right-back this month to provide competition to Reece James, who is currently out injured.
Inter Milan are looking for a significantly higher fee for the Netherlands international, with the report claiming the Serie A club are demanding at least €55m (£48.4m) for the 26-year-old.
Speaking last week, Dumfries’ agent refused to rule out the possibility of a move away from Inter before the end of the window.
“He’s an inter player now, and then we’ll see what happens in the future,” Rafaela Pimenta told RAI.
