The midfielder has made it clear he wants to leave Chelsea and Conte has decided that Matic will be better placed in England to secure a move away, rather than flying with the travelling squad on Monday.
Matic had been hoping to join
Manchester United, who remain in the market for a midfielder of his type.
But that is unlikely to stop Matic leaving and sources close to the Serb remain convinced he could still move to United, despite the Lukaku saga making such a transfer seem unlikely.
Despite wanting to leave, Matic attended the first day of pre-season training but spent the afternoon running on his own with a trainer.
Chelsea’s players took that as a sign that Matic will soon by leaving and it now remains to be seen whether or not he goes to United or elsewhere.
