Chelsea are watching Marseille midfielder Maxime Lopez.
The Sun says Blues boss Antonio Conte has instructed scouts to keep a close eye on the 19-year-old midfielder.
Lopez is yet to agree a new deal on his contract with the French outfit that expires in the summer, and that could prompt Chelsea into making a move for him at the end of the campaign.
The Frenchman has scored one goal and provided five assists in 16 games for Marseille this term.
