Chelsea rogue striker Diego Costa has not been included in Chelsea's 2017/2018 Champions League squad.
Costa was registered in Chelsea 25-man squad for the English Premier league season but not for their campaign in the UEFA champions league.
The wantawayvstriker is currently on strike in his homeland Brazil and doesn't want to come back to Stamford Bridge this summer.
He has set his heart on a return to his boyhood club, Atletico Madrid, but after the Spanish transfer deadline passed on Friday night he remained tied to the London club.
Nevertheless, for the Champions League it is evident Costa has no chance of playing a role even if he stays in London for another four months until the January window opens.
it remains to be seen whether he will pull on the blue shirt again despite being in Antonio Conte's team for the Premier league.
This decision was taken after Chelsea failed to complete transfers for Fernando Llorente and Ross Barkley on Deadline Day, leaving Conte short of options.
The row between Costa and Conte has become public after the Brazilian born Spaniard accused his manager of disrespect after the infamous text message that he doesn't have a future in Stamford bridge.
As it stands Costa has remained in his homeland Brazil and he has insisted that he has no plans to return to Chelsea or play for the club again after accusing them of treating him like a “criminal”, a claim laughed off by Conte.
It is clear that owner Roman Abramovich is especially determined to make him pay for defying the club with his rebellious behaviour.
