Wilfried Zaha scored the winner as Crystal Palace stunned reigning champions Chelsea to pick up their first victory of the Premier League season.
Palace had lost all seven of their previous games - including three under new boss Roy Hodgson - and had failed to score.
They finally ended their 731 minute wait for a goal when Yohan Cabaye forced the ball down off his chest, which bounced off David Luiz and into the back of the net off Chelsea defender Cesar Azpilicueta.
Palace's lead lasted only eight minutes as Cesc Fabregas' corner was headed in by Tiemoue Bakayoko.
But Zaha, on his return from injury, made it 2-1 just before the break and Hodgson's side held on despite an onslaught from the Blues in the second half.
The win does not move Palace off the bottom of the table, but they have reduced the gap from safety to four points.
Chelsea, meanwhile, stay fourth but are now nine points behind leaders Manchester City.
Meanwhile, Tottenham recorded their first Premier League victory at Wembley as Christian Eriksen's second-half winner saw off a resolute Bournemouth.
Chris Wood's header five minutes from time rescued a point for Burnley against 10-man West Ham at Turf Moor.
And Swansea City earned their first home win of the Premier League season to lift the pressure on manager Paul Clement.
Two goals either side of half-time from Chelsea loanee Tammy Abraham proved decisive as Huddersfield paid the price for making mistakes at both ends to make it seven games in a row without victory.
