Arsenal inflict only Manchester United's third defeat of the campaign in dramatic fashion. Chelsea boss Jose Mourinho must be dancing on King's Road now.

1752: GOAL Arsenal 2-1 Man Utd
Quite an extraordinary finish. Emmanuel Eboue delivers a pinpoint cross from the right that Thierry Henry powers past Edwin van der Sar with a terrific header. Is it the winner?
1749: Cristiano Ronaldo gets a great standing ovation from the home fans as he comes off to be replaced by Gabriel Heinze. Actually, that's a lie. The Portugal winger is booed off, as expected.

1727: Arsenal's Tomas Rosicky curls an 20-yard shot wide of Edwin van der Sar's goal after slick passing around the edge of the area.

1628: United's Patrice Evra makes a reckless challenge on Alexander Hleb and gets a booking. He does it under the nose of Arsenal boss Arsene Wenger who looks suitably unimpressed.

1611: Good pressure from the home side. Thierry Henry and Emmanuel Adebayor link up well on the left. The resulting corner comes to nothing.

1606: United's midfield make Arsenal dance all over the place. Paul Scholes lays the ball into the path of Ryan Giggs. The Welsh wizard curls his effort wide of Jens Lehmann's goal.
1604: United put Arsenal under early pressure. A Ryan Giggs free-kick is cleared but Philippe Senderos concedes a corner under little pressure. The corner comes to nothing.
1601: Manchester United kick off at the Emirates Stadium.
1557: The players come out of the tunnel for promises to be an entertaining clash. Well, hopefully more entertaining than the one at the JJB Stadium earlier.
1554: A packed house awaits for the players to re-emerge from the tunnel. A win for the Gunners would put them a point behind third-placed Liverpool. Perhaps more importantly just six behind second-placed Chelsea and that automatic Champions League spot.
1551: Brazil international Gilberto gets Arsenal's player-of-the-month award. Well done.
1546: Just 14 minutes before kick-off and the players are out for their warm-up on the fantastic looking Emirates Stadium pitch.

1529: Arsenal make three changes with Mathieu Flamini, Emmanuel Adebayor and Emmanuel Eboue coming in for Justin Hoyte, Robin van Persie and the suspended Gilberto Silva. Manchester United make one change, with Ryan Giggs returning to the starting line-up in place of Ji-Sung Park, while Louis Saha, who has been suffering from a groin injury, takes a place on the bench.
1525: FULL-TIME Wigan 0-2 Everton

1520: GOAL Wigan 0-2 Everton

1446: Wigan keeper Chris Kirkland collides with Everton striker Andrew Johnson inside the penalty area. Johnson appears to have suffered a serious leg injury and is stretchered off, covering his face as he is taken into the tunnel. Victor Anichebe comes on to replace him.
1444: Probably the best chance of the match. Wigan fail to deal with an inswinging corner, but the unmarked Joseph Yobo heads his effort a foot wide of the far post.
1442: Everton defender Joseph Yobo is caught in the chest by the boot of Lee McCulloch who was attempting an overhead kick. The Nigeria international gets up after spending 10 seconds on the deck.
1441: It's raining.
1434: Wigan kick off the second half. The crowd live in hope the match may become an entertaining affair.
1418: HALF-TIME
Referee Howard Webb allows just over a minute of stoppage time. That was perhaps the biggest talking point of the half.
1415: Everton's Joseph Yobo is booked for tripping over Emile Heskey.
1412: This has to go down as one of the worst 45 minutes of Premiership football ever.
1407: The biggest cheer of the day is an ironic one from the home fans when referee Howard Webb awards Wigan a free-kick for a foul on Lee McCulloch.
1403: It's 8C today in Wigan. Quite warm for January. Do you blame global warming?
1401: Leighton Baines tries to alleviate some of the boredom that has descended upon the JJB Stadium with a fierce strike from 25 yards. But his shot rises high over Tim Howard's goal. The crowd retreat back into their slumber.
1352: Everton exchange cute passes around the edge of the area. The ball finally arrives at the feet of Tim Cahill. But the midfielder's sidefooted effort from 18 yards out fails to trouble Chris Kirkland.
1348: There are probably more people at one of chairman Dave Whelan's JJB Sports outlets than at his stadium today. Another far from packed house.
1341: Emile Heskey is putting himself about a bit for Wigan. He lays the ball off to team-mate Kevin Kilbane who rifles his 20-yard shot from the left two feet wide of Tim Howard's left-hand upright.
1338: Luis Valencia's shot from the right side of the area smashes into the side netting.

606 DEBATE: Your thoughts on Sunday's Premiership games
Wigan will be looking to bring to an end the longest losing run in the Premiership this season - six on the bounce. It will be interesting to see if Lee McCulloch puts his whole heart into the game having had a transfer request rejected by the club this week.
Everton, this week without the aid of Sylvester "did I mention I'm starring in Rocky XI?" Stallone, are hoping their season has some sort of silver lining having been knocked out of all the cup competitions.
They are five points off sixth spot, so a win at the JJB would go down a treat with the blue half of Merseyside.
Meanwhile, Birmingham boss and former Manchester United defender Steve Bruce believes his old club, leading the league by six points, will win the title.
In his least outlandish comment of the year, he told BBC Five Live on Sunday: "I thought right from the start that Manchester United would be favourites to win the title.
"The younger lads, Wayne Rooney and Cristiano Ronaldo, are a little bit mature now.
"They also have the player of the season, in my opinion, who is Paul Scholes and the team also have got a little bit of momentum going."
Watch out Nostradamus.
United play Arsenal in our 1600 GMT game.
