Donervon Daniels has put through his own net to hand an equaliser to Norwich City as Neil Adams's side, who are on a seven-game unbeaten streak in the league, look to avert a potential upset at Bloomfield Road after Nathan Delfouneso handed 23rd-placed Blackpool a 1-0 lead.

With Nottingham Forest being held 0-0 by Sami Hyypia's Brighton at the moment, Watford could go level on points with the league leaders as goals from Matej Vydra and Daniel Tozser has given them a 2-1 lead at Blackburn Rovers.

"Leicester are two down at Crystal Palace. Unless the Foxes turn this around like last week I think our chances of winning the league will be remote."

"That's an easy header for Diego Costa because he made it look so easy. Fantastic.

"We know how well Chelsea can craft build-up play, and Costa saw a gap of two or three yards, made it, and then a really strong header on the move. A couple of earlier headed chances were missed because he was static but this time on the move he got past the defence and ahead of Brad Guzan.

"Lovely movement and a lovely effort, and that's why he keeps scoring goals."

That makes things interesting. Wayne Rooney sees red for a wild kick at Stewart Downing in full flight. An ugly dismissal, but referee Lee Mason deemed the challenge high, dangerous and it prevented West Ham from breaking.

Chelsea's best move of the match sees great inter-play between Eden Hazard and Cesar Azpilicueta, who then delivers a pinpoint cross for Spain striker Diego Costa to nod in from eight yards for his eighth of the season.

Lovely goal by Southampton as Sadio Mane superbly backheels the ball into the path of Ryan Bertrand and he finishes with aplomb. Deserved for the hosts.

Chances at either end at Stamford Bridge as Nathan Baker cushions a header on to the roof of the Chelsea goal, before the hosts pop down the other end of the pitch and Diego Costa nods a downward effort into the hands of Brad Guzan.

Managerless Leyton Orient, who have the worst home record in the division and parted company with Russell Slade this week, have fought back from a goal down to lead 2-1 against Rochdale at Brisbane Road - Roman Vincelot adding to Jobi McAnuff's equaliser.

Meanwhile, a Keiran Agard brace has given league-leaders Bristol City a 2-0 advantage in their top-of-the-table clash with second-placed MK Dons at Ashton Gate. As it stands, City will move eight points clear of the visitors.

Peterborough are looking to keep the pressure on at the top and Darren Ferguson's side lead 1-0 against Fleetwood at London Road - Conor Washington netting just before the break.

The second half in the game between Southampton and QPR is back under way, by the way. Still goalless, but the hosts are well on top.

Mitch Mansfield:, external Had Eliaquim Mangala not made his (excellent) debut last week, he'd be rivalling Jonathan Woodgate's Real Madrid bow today.

Woodgate scored a spectacular own goal and was sent off against Athletic Bilbao on his Real debut in 2005.

"Villa, all of a sudden, have felt their way into this game. They're just starting to up the pressure a little bit more and asking a few questions of Chelsea."

David De Gea keeps Manchester United ahead with a point-blank save from Diafra Sakho's angled shot.

"Crystal Palace's first goal, I scored a few goals like that in my time. Fraizer Campbell is standing right in front of the goalkeeper at the corner and he just touches it in. Then he wheels off in celebration as if he has scored the goal of the season. That's because he is a striker - good luck to him!"

Make that two for Palace, with Mile Jedinak heading home Jason Puncheon's free-kick from 12 yards out.

If you thought Phil Jagielka could hit a ball, you ain't seen nothing yet. Yaya Toure rattles the Hull post with an absolute sizzler from 35 yards. How did that not go in?

Swansea boss Garry Monk is fuming on the touchline as Swansea are denied a decent shout for a penalty. Wayne Routledge weaves his way towards the area and is stopped by Santiago Vergini just inside. Referee Chris Foy is not interested though.

The Eagles have flight. A corner is powerfully headed towards goal by Scott Dann and Fraizer Campbell gets the decisive touch with a flick from four yards.

Chris at work: Manchester United are above Liverpool - who's in crisis?

Mo in Leicester: Surely Van Gaal must realise that with a soft centre United need two holding/sitting players in front of the defence. No need for three strikers!

Keith: Scoring goals for fun is no good if you can't defend properly. But which Manchester club am I talking about?

Aston Villa try to fashion a quick equaliser after the start of the second half as Fabian Delph fizzes a shot just wide, Chelsea keeper Thibaut Courtois diving just to be safe.
