Chelsea are tracking AS Monaco attacker Malamine Efekele.
Foot Mercato says Chelsea and Valencia are watching the 19 year-old, who is yet to make his Ligue 1 debut.
The France U20 international is tied to Monaco until the summer of 2025.
Efekele's form in youth football has drawn comparisons with PSG star Kylian Mbappe.
The youngster plays primarily as a winger, but can also play centrally.
