Alvaro Morata and Michy Batshuayi proved there is life after Diego Costa as Chelsea fought back to win 2-1 at Atletico Madrid.
Costa, whose return to Atletico was completed on Tuesday, watched on as Chelsea responded from David Luiz's needless concession of a penalty scored by Antoine Griezmann.
Former Real Madrid striker Morata headed in Eden Hazard's cross for his seventh goal in eight games for Chelsea, before Batshuayi struck with the final kick of the game.
The dramatic finish gave the Blues two wins from two Champions League Group C games.
