Antonio Conte's Chelsea snatched victory right at the death against Atletico Madrid as they came from behind to snatch all three points courtesy of Michy Batshuayi's last ditch strike.
Alvaro Morata's second half header had initially cancelled out Antoine Griezmann's 40th minute penalty but the Belgian forward came off the bench to grab the winning goal.
It was an encouraging display in parts for the Blues, as they faced established European opposition in just their second group game, and they may look back on this game as a point well earned in Atletico's Wanda Metropolitano stadium.
