It was a sixth Premier League defeat in a row for the Blues for the first time since 1993.

The Blues came from behind to ease to victory over Unai Emery’s team.

Jarrod Bowen and Crysencio Summerville put the Hammers in control, but goals from Joao Pedro, Marc Cucurella and Enzo Fernandez snatched the points.

Chelsea looked safe with an early lead given to them by Enzo Fernandez’s penalty.

Joao Pedro showed lightening-quick thinking to net when a ricochet fell his way before a penalty from Cole Palmer doubled their score.

Goals at the start of each half earned Brighton a fourth victory from their last six Premier League matches.
