Reports in France have claimed that Chelsea are looking to sign the brother of recent recruit Eden Hazard.
Thorgan Hazard, 19, who currently plays for Lens in France, is believed to be a transfer target of the Blues.
Chelsea completed the signing of 21-year-old Eden earlier this summer from Lille for a fee of £32m.
The Belgian international may now be joined at Stamford Bridge by his sibling, with Chelsea having made contact with Lens over their youngster's availability, according to L'Equipe.
The younger Hazard brother has made just 11 appearances at senior level.
