Manchester United lose top spot after shock defeat to Norwich City

Manchester United were humbled 1-0 by Norwich City and Chelsea upset at West Bromwich Albion on Saturday as champions Manchester City took advantage of their rivals' mistakes to go top with a 5-0 demolition of Aston Villa.

United, who suffered their third Premier League defeat of the season in the late kickoff at Carrow Road, succumbed to a 60th-minute header from their former youth team player Anthony Pilkington.

Chelsea lost 2-1 at West Brom, with Peter Odemwingie's second-half winner sending the home side into fourth place and ruining the return of former Baggies manager Roberto Di Matteo.

City's victory at the Etihad Stadium, engineered with two goals apiece from Argentine duo Sergio Aguero and Carlos Tevez, took them top of the league for the first time this season.

Roberto Mancini's side have 28 points from 12 matches, with United second on 27 points. Chelsea have 24 points from 12 games with Albion a point further back.

Arsenal had kickstarted their season in the early Saturday kickoff by beating north London rivals Tottenham Hotspur 5-2 after Spurs striker Emmanuel Adebayor was sent off for a reckless first-half challenge on Santi Cazorla.

In-form Luis Suarez scored twice to help Liverpool to a 3-0 win at home to Wigan Athletic, who lost midfielder Ben Watson to a broken leg, while Swansea City enjoyed a 2-1 victory at a struggling Newcastle United.
