It was reported in Spain last night that he is already back in London to resolve his future with the west London club, but Standard Sport understands that is not the case.
The 28-year-old has been AWOL in Brazil since mid-July, but he is being encouraged by the Spain national team and Atletico Madrid, who want to buy him in January, to make peace with Chelsea and work on his fitness.
Costa claims he was told he was no longer wanted by Conte via text message in June, which was the last time he played a competitive game.

8/8 June 2017
Costa revealed at the end of a title-winning season that Conte had texted him to say the striker was no longer part of his plans at Stamford Bridge. The Spaniard’s public declaration was eventually embarrassing as Chelsea missed out on No.1 target Romelu Lukaku to Manchester United, leaving the Blues with no marquee deal and a wantaway forward in Costa.
The forward has been training on his own in Brazil, but is believed to be several weeks away from being ready to play competitive football.
Atletico hesitated about buying him this summer as they can’t register any new players due to a Fifa transfer ban until the new year, but they do want him ready to join them in four months’ time.
Meanwhile, Spain won’t consider him for their World Cup plans next summer unless he is back playing and scoring goals regularly again.
Some of his Chelsea team-mates are also understood to be in contact with the striker and have been urging him to return to Stamford Bridge.
Chelsea named him in their Premier League squad last week, but left him out of their Champions League group.
