Jon Walters scored two own goals
Jon Walters scored two own goals and missed a penalty as Chelsea thumped Stoke to end the Potters' 17-game home unbeaten run in the Premier League.
Walters headed a Cesar Azpilicueta cross into his own net just before half-time and repeated his unwanted trick from a Juan Mata corner, reports the BBC.
Frank Lampard made it 3-0 from the spot after Mata was fouled and Eden Hazard smashed in a fourth from 30 yards out.
Walters' misery was completed when he blasted a late penalty over the bar.
And three goals in the final nine minutes gave Reading an unlikely win over West Brom.
Two goals from Romelu Lukaku either side of half-time had given the dominant Baggies a deserved lead.
But Jimmy Kebe pulled one back before Adam le Fondre's penalty drew the home side level with two minutes to go.
Pavel Pogrebnyak dived in from close range to put Reading ahead on 90 minutes and they hung on for only their third win of the season.
And Queens Park Rangers continued the road to a tough recovery when they played out a gritty goalless draw with Tottenham Hotspurs in the early kickoff of the Premier League on Saturday.
Shaun Wright-Phillips failed to recreate the heroic goal against Chelsea, as he missed a host of chances in both halves.
Emmanuel Adebayor and Jermain Defoe were the culprits for the visitors as they also missed chances that could have either settled the nerves, or decided the tie, with QPR keeper Julio Cesar tipping a Jermain Defoe shot onto the post and saved Emmanuel Adebayor's follow-up early on.
Adel Taarabt was his magnificent self in the heart of QPR midfield, but he could not find the incisive pass that could split the Spurs defence, and neither could he find a shot to earn the full points.
QPR 0 - 0 Tottenham
Aston Villa 0 - 1 Southampton
Everton 0 - 0 Swansea
Fulham 1 - 1 Wigan
Norwich 0 - 0 Newcastle
Reading 3 - 2 West Brom
Stoke 0 - 4 Chelsea
Sunderland 3 - 0 West Ham
