Chelsea are interested in AS Monaco midfielder Youssouf Fofana.
Nice-Matin says four unnamed Premier League clubs are showing interest in Fofana, with Chelsea raised as a prospective destination.
At the same time, interest from rival Paris Saint-Germain has cooled.
France international Fofana has a contract with Monaco until 2025.
The 24-year-old has scored two goals and provided one assist in 42 competitive appearances for Monaco this season.
