A bright start from Sunderland in the first half.

Full-back Bryan Oviedo's inch perfect pass plays Fabio Borini through on goal, but the Italian's finish is tame and straight into the hands of Burnley goalkeeper Tom Heaton.

Everton have dominated the game, they are passing the ball well, it's a real professional performance.

It's a pretty even game. 

They both want to win the physical side of it but are forgetting to score goals and win football. Stoke have been putting everything they have into the box. They're putting Chelsea under pressure. 

Despite getting a kicking in the first half, Diego Costa has emerged for Chelsea after the interval.

I make it just Joe Allen who did not put the boot in on the Spaniard for Stoke.

He's wise to stay clear.

The half-time highlights reel contained five replays of a scuffed half chance that went well wide, that's how bad the first half was.

There's a change in personnel for the second half with Valon Behrami having failed to emerge for Watford, Abdoulaye Doucoure is on in his place.

Where are the twists and turns coming from in the second half?

We are back under way.

West Brom got their tactics spot on, they defended and made it difficult for Arsenal to break them down. 

When West Brom went ahead I said "ooh look at Arsenal coming back!' - That surprised me, I didnt think they had that in them at all. Then the capitulation started. West Brom were relenteless. 

The Arsenal defence couldn't handle it. 

West Bromwich Albion

West Brom manager Tony Pulis speaking to Match of the Day: "I think everybody's got to calm down. You're always going to have runs of games where you don’t pick points up. You raise the expectation and people get carried away. 

"The lads have worked so hard in all the games. I thought we’d never play as well as what we have played. They’ve never given anything but their best.

"The lads were a bit disappointed with two defeats. They’ve done fantastically well. They’ve carried on working so hard together as a group. I thought on the counter we always looked dangerous.

"We’ve got 43 points. We know where we are as a football club. We’re not getting carried away. 

"We’ll do the best we possibly can. If we win games, brilliant. If we don’t we’ve still got a group of honest players who give everything."

Arsenal

Arsenal manager Arsene Wenger speaking to Match of the Day:  "It was a typical Premier League game. A team that likes to play and a team that defends well. 

"It was a tough performance. They caught us on set pieces and one break and that made the difference.

"Overall our record against set pieces is quite good. We were a bit naïve, maybe, on the corners. Then we were punished. It’s a shame. We looked in the second half to take completely over.

"We didn’t create enough. We lost Alexis Sanchez in the second half, he was very dangerous in the first. He came out in the second half and he couldn’t move any more. In the first half he was a guy who created a lot.

"It leaves us in a unique situation that we’ve never had before. We face big problems to regroup and find resources to sort out the problem. We need some togetherness.

"We face some serious challenges. The City game at home is a big game for us."

Will he stay or will he go?

Here is reaction from Arsenal's loss at West Brom...

In the Championship, Fulham - currently in sixth - have gone 1-0 down at home to 19th placed Wolves, after Ivan Cavaleiro tapped in from close range. 

Meanwhile it's still 0-0 at St Andrew's, where league leaders Newcastle have traveled to face Birmingham, while Burton have taken a 3-1 lead over Brentford.

In League One, Franck Moussa has scored twice in 10 minutes for Walsall against fellow promotion chasers Southend. They're 2-0 up.

An action-packed first half at the Bet365 Stadium, with Diego Costa heavily involved, but it is all square at the break.

Three shots on target = three goals. 

Leicester in control at the break.

Burnley should be ahead at the interval, but find themselves goalless against the Premier League's bottom side.

Scott:  Costa’s technical ability as a player is great, but his attitude and behaviour on the pitch is staggeringly awful. 

David Simpson: If I were a Chelsea fan, I'd say to him what I tell my U9 team. "Stay on your feet, you can't help us on the floor!"

Jon Connor: Stoke's game plan - Kick Chelsea off the park it seems!

Phil Bardsley has kicked Diego Costa right on the outside of the knee and taken the Chelsea striker down.

Stoke boss Mark Hughes has set his team out to do a specific thing...and it is working.
