Arsenal returned to winning ways after three consecutive draws in all competitions, as an Alexis Sanchez double saw them to a 3-1 victory over Bournemouth at the Emirates Stadium on Sunday.
Manchester United drew a fourth consecutive home Premier League game, as they managed only a 1-1 result against West Ham United at Old Trafford.
Meanwhile, Heurelho Gomes' own goal earned Stoke City a 1-0 win against Watford at Vicarage Road, and Southampton beat Everton 1-0 thanks to Charlie Austin's opening-minute strike.
Here is how the Premier League standings now look following Sunday's action:
|Premier League Standings|
|9||West Bromwich Albion||13||4||5||4||17||16||1||17|
|16||West Ham United||13||3||3||7||14||24||-10||12|
Arsenal had to work hard for their victory against manager Eddie Howe's Cherries. Sanchez put them 1-0 up in the 12th minute following Steve Cook's calamitous backpass.
But following Callum Wilson's equaliser from the penalty spot 11 minutes later after a foul by Nacho Monreal, Bournemouth then had several excellent chances to go ahead.
As it was, Theo Walcott restored the Gunners' lead when he headed home Monreal's cross soon after the break, and Sanchez got his second in stoppage time following an excellent break involving Mesut Ozil and Olivier Giroud.
Per Sky Sports Statto, it was a fine performance from the Chilean and put Arsenal back within three points of league leaders Chelsea:
United slipped 11 points back from the Blues, as they failed to earn a win against the struggling Hammers.
It was the visitors who took the lead at Old Trafford after just over a minute when Diafra Sakho headed home Dimitri Payet's inch-perfect free-kick from the right.
Zlatan Ibrahimovic then equalised 20 minutes later, as he nodded a glancing header from a superb Paul Pogba ball past Darren Randolph.
United then proceeded to have a number of excellent chances but were thwarted on several occasions by an impressive Randolph, and when they did have the ball in the back of the net again in the second half, the goal was rightly ruled out for offside.
Red Devils manager Jose Mourinho spent most of the match away from the dugout having been sent to the stands for his reaction to a Pogba booking.
Per WhoScored.com, United and their manager have some problems to resolve at home:
Everton fell to a third defeat in five league matches, as they were undone by Austin's goal after 41 seconds at St. Mary's.
It was a disappointing return to Saints for Toffees manager Ronald Koeman, as he saw his side go 1-0 down after Austin headed home from close-range. The 19-year-old debutant Josh Sims set up the goal.
Everton had their chances to earn a point including a frustrating miss by Idrissa Gueye, but it was the hosts who came away with the victory.
Meanwhile, Stoke's 1-0 win at Watford came courtesy of Gomes' 29th-minute own-goal, Charlie Adam's header ricocheting home off the Hornets goalkeeper after it had hit the post.
