Manchester City winger Raheem Sterling hits hat-trick to sink Bournemouth
Raheem Sterling hit his first senior hat-trick as Barclays Premier League leaders Manchester City swept aside Bournemouth 5-1 at the Etihad Stadium.
City were without injured duo Sergio Aguero and David Silva, but Sterling shouldered the attacking responsibilities against a Cherries side suffering even worse fitness problems.
The England winger opened the scoring in the seventh minute and netted twice more before the interval.
Wilfried Bony was also on target in either half, while Glenn Murray briefly gave his side hope at 2-1.
Arsenal ended the day two points behind Ciy following a 3-0 away win at Watford.
The Gunners were held at bay for an hour but the Hornets were torn apart in a decisive 12-minute spell that saw Alexis Sanchez, substitute Olivier Giroud and Aaron Ramsey all find the target.
For Sanchez it was the continuation of a rich vein of form that has now brought 10 goals in his last six games for club and country.
Manchester United sit level on 19 points with Arsenal after Wayne Rooney capped a 3-0 win with his 187th Premier League goal.
That put him level with former Red Devil Andy Cole in second on the league's all-time list, behind only Alan Shearer.
Morgan Schneiderlin got things started with his first goal for the club after 18 minutes, followed by Ander Herrera's effort soon after.
Rooney benefited from a Phil Jagielka error to net his second league goal of the season against his former club.
Jurgen Klopp's hotly-awaited bow as Liverpool boss ended with a goalless draw at Tottenham.
The result might have swung either way, with Divock Origi heading against the crossbar for the Reds, whose goalkeeper Simon Mignolet needed to be at his best to maintain a clean sheet at the other end.
At Stamford Bridge, Diego Costa returned from suspension to ease the pressure on manager Jose Mourinho.
Costa netted both goals in a 2-0 win over struggling Aston Villa, trebling his league tally for the season.
The Sam Allardyce effect yielded no immediate rewards for Sunderland, who remain winless this term following a 1-0 loss at West Brom.
Saido Berahino's reintegration at the Hawthorns continued as he snaffled the ball from Costel Pantilimon's grasp to poke home the winner in the 54th minute.
West Ham scored twice in the closing moments to see off 10-man Crystal Palace and grab a fourth away win of the campaign.
The score was tied at 1-1 after Carl Jenkinson's opener and Yohan Cabaye's twice-taken penalty when Dwight Gayle collected a second yellow card just before half-time.
The Hammers' laboured without result until the 88th minute when Andy Carroll's knockdown was finished by Manuel Lanzini before Dimitri Payet made it 3-1.
Jamie Vardy's stellar start to the season continued as he hit the target twice to salvage a point for Leicester at Southampton.
Saints looked safe after first-half goals from defenders Jose Fonte and Virgil van Dijk, but the division's top-scorer made it nine for the season, pouncing in the 67th and 90th minutes.
