Tiemoue Bakayoko has undergone his Chelsea medical ahead of his £35million move from Monaco, the Sun has claimed.
The Frenchman will become manager Antonio Conte's first summer signing.
The midfielder will add depth to a department that is expected to lose Nemanja Matic who will join Manchester United.
One man who is not amused by the transfer is former midfielder Ray Wilkins who urged his former club to sign a different player or at least give an opportunity to Nathaniel Chalobah.
"I was really disappointed to read they are looking at Bakayoko from Monaco," Wilkins said on talkSPORT.
"He is 22 years of age, French and doesn't get near the national side, but it was quoted Chelsea might be paying £32million.
"Well, in Nathaniel [Chalobah] they have got a footballer that can play exactly the same but just needs an opportunity to get in there and play.
"You have seen already in the two games he has played up to now [at the European Championship] he looks a class act in and amongst people of his own age.
"Playing with the top quality players that they have at Chelsea, he can only improve week to week."
