Rodrigo Muniz capped off a stunning late Fulham comeback at Stamford Bridge to deal a major blow to Chelsea's Premier League title hopes.
The Brazilian's 95th-minute winner came shortly after former Liverpool youngster Harry Wilson looked to have stolen a point for the Cottagers against their regular tormentors.
Enzo Maresca's side led for most of the game at Stamford Bridge through Cole Palmer's stunning first-half strike.
Palmer netted his 12th Premier League goal of the season after a superb turn and finish, which would have taken the Blues to within a point of the leaders ahead of their home clash against Leicester.
