Ollie Watkins came off the bench to score a second-half double as Aston Villa came from behind to beat Chelsea.
The Blues had led through Joao Pedro’s first-half strike, before Watkins equalised after being played through by Morgan Rogers.
And he put the Villains in front with a powerful header from a corner to make it 11 wins in a row in all competitions for Unai Emery’s side.
The victory also keeps them within three points of league leaders Arsenal. Chelsea, meanwhile, are fifth, 13 points behind the Gunners.
