Chelsea are interested in a loan deal for Real Madrid Sergio Reguilón as Frank Lampard looks for a new left-back this summer.
The Blues are undergoing an overhaul under Lampard this summer, with Hakim Ziyech and Timo Werner already signed up.

Leicester’s Ben Chilwell has been named as Chelsea’s top target for most of the last year, but the Foxes are not keen on selling, and the Blues are looking elsewhere.
