Chelsea are hoping to secure the signing of Sergio Reguilon from Real Madrid.
The left-back has spent the past season on loan at Sevilla, where he was very impressive.
Now the 23-year-old is subject of a bid from the Blues, per ESPN.
The source claims Chelsea are struggling to agree with Leicester City on a fee for Ben Chilwell.
It may appear they have moved on to Reguilon as the next option, or the links could be a way to drive down the price for Chilwell.
The move for the Spanish could be a one-year loan, or a direct purchase of roughly €25 million.
