Chelsea are interested in signing Lyon wonderkid Malo Gusto, according to French newspaper L’Equipe via The Sun.
His performances have earned him seven France under-21 caps and a reputation for being one of the world’s best young full-backs.
Gusto has 18 months remaining on his Lyon contract but the French side want to keep him until the end of the season.
The teenager has already made over 50 appearances for Lyon and has been a regular this season.
Chelsea have spent £186.5m in the last three weeks, on David Datro Fofana, Andrey Santos, Benoit Badiashile, Mykhailo Mudryk and Noni Madueke.
The Blues also paid a £10m loan fee to sign Joao Felix from Atletico Madrid until the end of the season.
