Liverpool hit four to stun City as Foxes go top
Liverpool blew away title favourites Manchester City with an emphatic 4-1 victory at the Etihad Stadium to leave Leicester top of the Barclays Premier League.
The Reds got off to a flying start as Raheem Sterling endured a day to forget against his old club, the visitors racing into a three-goal lead thanks to an own goal from Eliaquim Mangala and strikes from Philippe Coutinho and Roberto Firmino inside 32 minutes.
Sergio Aguero marked his return from injury with a superb effort to reduce the arrears just before half-time, but Martin Skrtel added to City's misery with a fourth for Liverpool.
Defeat denied City the chance to return to the top of the table, with Leicester instead taking over at the summit thanks to a 3-0 win earlier in the day at Newcastle.
Jamie Vardy scored for the 10th consecutive Premier League game to equal Ruud van Nistelrooy's record.
The Foxes forward shook off pre-match concerns over a hip injury and blasted home in first-half stoppage-time to match former Manchester United striker Van Nistelrooy's streak set in 2003.
Leonardo Ulloa laid on the record-equalling effort before heading home himself, and substitute Shinji Okazaki added another as Leicester's incredible season continued.
It meant Claudio Ranieri's men moved above lunchtime leaders United, who won 2-1 at Watford, and the two sides meet next weekend at the King Power Stadium where Vardy can make history.
At Vicarage Road, Watford looked to looked to have snatched a point when Troy Deeney's 87th-minute penalty cancelled out Memphis Depay's opener, but the Hornets captain bundled B astian Schweinsteiger's cross into his own net moments later to ensure an away win.
Arsenal would have gone top had they won at West Brom, but they blew their chance as Santi Cazorla missed a late penalty.
James Morrison and Mikel Arteta's own goal cancelled out Olivier Giroud's first-half opener as the Gunners suffered a frustrating afternoon and lost 2-1 in the Black Country.
Cazorla slipped and skied his spot-kick in the final 10 minutes and Mesut Ozil hit a post, but Arsenal could not recover from a nightmare five minutes just before half-time.
Jose Mourinho was back in the dugout and Diego Costa returned to the score sheet as Chelsea claimed a much-needed 1-0 win over Norwich.
Costa ended a six-match barren spell as the champions secured only a fourth win in their 13th league game of the season.
Bottom side Aston Villa slumped to a heavy first defeat under Remi Garde in his second game in charge as two goals apiece from Ross Barkley and Romelu Lukaku condemned the bottom club to a 4-0 thrashing at Everton.
Barkley put the Toffees ahead in the 17th minute, finishing at the far post after Brad Guzan had turned Gerard Deulofeu's effort his way.
Lukaku headed home in the 28th minute before poor Villa defending allowed Barkley to add another three minutes before half-time.
Belgium forward Lukaku notched his second just before the hour, with Barkley and Deulofeu again involved.
At St Mary's Bojan Krkic fired away-day specialists Stoke to a 1-0 victory against Southampton.
The former Barcelona forward tucked in his third goal of the season after 10 minutes.
Andre Ayew came to Garry Monk's rescue as Swansea fought back from a two-goal deficit to draw 2-2 with Bournemouth.
Joshua King and Dan Gosling had fired the visitors into a commanding lead after 26 minutes to give the Cherries hope of a first win in eight games.
Ayew pulled a goal back within two minutes of Gosling's strike with a classy back-heel and then won a penalty, albeit in dubious circumstances, which Jonjo Shelvey stroked home before the break.
