Chelsea are reportedly continuing to work on a deal with teenage defender Xavier Mbuyamba following his release by Barcelona.
The Dutchman, who has been likened to Liverpool defender Virgil van Dijk because of his playing style, left Camp Nou last month and has a pick of clubs to choose from.
Mbuyamba trained with Chelsea during his time with Barcelona and, according to the Daily Mail, the Blues are in talks to sign the 18-year-old.
Speaking earlier this year, the youngster's agent Carlos Barros revealed that "almost all major clubs in Europe have asked about Xavier".
Mbuyamba made just three appearances for Barcelona in last season's UEFA Youth League.
