It means the Blues’ rebel striker is now under more pressure than ever to return to England and resolve the stand-off that is overshadowing the start to the season. The two clubs are keen to do a deal, even though they are miles apart on their valuations. Chelsea are asking for £50million, but Atletico are only ready to pay half that. The Spaniard has been AWOL for five weeks after a text row with boss Antonio Conte. And there has been little sign of a breakthrough in the whole tit-for-tat row. Costa, 29, has said he only wants to play for his former club in Spain now he has no future with the Premier League champions. But the summer-long saga is in limbo while the player refuses to bow to Chelsea’s demands to come back to England and resume training.
