Chelsea held talks with Inter Milan on Saturday about a deal for Matias Vecino.
The Uruguay midfielder is a favourite of Chelsea manager Maurizio Sarri and has been recommended to the Blues board.
The Daily Star says Chelsea and Inter took advantage of their International Champions Cup meeting to discuss a price for Vecino.
The Uruguay international did not feature because he is still recovering from his exploits at the World Cup.
Chelsea have completed two signings so far in the summer transfer window but look set to step up their activity ahead of next month's deadline.
Blues director Marina Granovskaia and Roman Abramovich are both in Nice to discuss the club's transfer targets.
Tiemoue Bakayoko has been linked with a move away from Stamford Bridge so the midfield remains an area of concern.
