Chelsea boss Antonio Conte won't register Diego Costa for his Champions League squad.
That's according to transfer guru Duncan Castles as speculation surrounding the Spain international's future rumbles on.
Costa was registered for the Premier League last night.
But on Twitter, Castles wrote: "Am told that Diego Costa has been excluded from Chelsea's Champions League squad."
Chelsea return to Champions League group stage action in September and are due to face Atletico, Roma and Qarabag.
