Attacker Diego Costa wanted to leave Chelsea, but this summer his wish did not come true.
The Spanish national team player was linked with Madrid's Atletico and other teams, but ultimately stayed in the English capital.
On Friday, Premier League clubs had to submit final player rosters to league organizers and the Blues' bosses decided not to leave D.Costa out and include him in the squad.
However, it is still unclear whether the striker will have the opportunity to perform within Chelsea - he has clashed with the team's head coach Antonio Conte in the press several times and has stated that he will not return to London.
In the past, D.Costa has played for clubs like Atletico or Valladolid.
