City profit as United and Chelsea stumble

Unexpected defeats for Chelsea and Manchester United allowed champions Manchester City to stroll into first place in the Premier League on Saturday by crushing Aston Villa 5-0.

United's 1-0 loss in the late kick-off at Norwich City prevented them from returning to the summit, while third-placed Chelsea have now gone four games without a win after losing 2-1 at West Bromwich Albion.

David Silva's scrappy 43rd-minute goal put City ahead at the Etihad stadium, before penalties from Sergio Aguero and Carlos Tevez made it 3-0.

Aguero beat Villa goalkeeper Brad Guzan at his near post to claim his second goal in the 67th minute and Tevez then tapped home the fifth, as City warmed up for Wednesday's vital Champions League encounter with Real Madrid in style.

The result dropped Villa into the bottom three and took City a point above United, who slumped to their third defeat of the campaign at Carrow Road.

Javier Hernandez started up front for the visitors after inspiring last weekend's 3-2 win at Villa, but it was former United trainee Anthony Pilkington who claimed the game's only goal with an excellent 60th-minute header. United's best chance of an equaliser saw Norwich goalkeeper John Ruddy produce a flying save to prevent Sebastien Bassong from scoring an injury-time own goal, as Chris Hughton's side held firm to claim another prized scalp after last month's 1-0 win at home to Arsenal.

Meanwhile, Chelsea's early-season momentum appears to have fizzled out completely after their defeat at coach Roberto Di Matteo's former club left them four points off the pace.

Shane Long put West Brom ahead at the Hawthorns with a 10th-minute header and then teed up Peter Odemwingie for what proved to be the match winner after Eden Hazard's header drew the visitors level six minutes before half-time.

West Brom's victory allowed them to climb to within a point of Chelsea and they clambered over Everton into fourth place after David Moyes' side were beaten 2-1 at Reading.

Earlier, Tottenham striker Emmanuel Adebayor scored but was then sent off as his former club Arsenal stormed back from behind to win 5-2 in the north London derby at the Emirates stadium. Elsewhere, in-form Luis Suarez took his tally for the season to 10 league goals with a brace as Liverpool beat Wigan Athletic 3-0.
