Costa has been on self-imposed exile in his native Brazil all summer after being told by boss Antonio Conte via text that he is no longer wanted at Stamford Bridge.
The 28-year-old declared in an interview last month that his Chelsea career is over , as he had no intention of returning to the Premier League champions and would instead hold out for a return to Atletico Madrid .
A transfer to his former side did not materialise during the summer window, however, meaning that the Spain international remains contracted to the Blues until at least January when Atleti are likely to return.
The Telegraph claims that Costa’s teammates expect him to give serious consideration to end his strike plans, however, having seen his stance soften in recent days.
Eden Hazard is among those to have called on the striker to end his feud with Conte after being included in the 25-man Premier League squad for this season.
