Roberto Martinez not happy with referee Jonathan Moss - but Jose Mourinho was...

And now for the bottom half:

Everton boss Roberto Martinez told BT Sport: "The result is hard to take. You believe you'll get what you deserve - we didn't.

"It was a performance full of spirit. Defensively we were very good and we created the best chances. There were a couple of world-class saves from Petr Cech.

"The second yellow card for Gareth Barry is very harsh. It's an unfortunate goal to give away, the ball goes through a players' legs. But it allows us to carry on with a good level of performance.

"My players were really upset about that [Branislav Ivanovic incident in the late melee]. It's the reaction of the Chelsea players you don't like. Ivanovic grabs James McCarthy by the throat. You need a strong referee for those matters. You have to take your chances. You don't want to see the incidents we saw at the end.

"I was disappointed with the manner in which the referee dealt with it."

Here's how the top half of the table now looks:

Fairly standard for Celtic at Patrick Thistle in the Scottish Premiership - they lead 3-0 with goals from Gary Mackay-Steven, Stuart Armstrong and Stefan Johansen.

Demola Oke: Manchester United are third. How that's possible, I really don't know...

Gamma: Pure luck for Chelsea. Mourinho has it down to a fine art.

Robin Smit: If Burnley played like they did for the first 60mins tonight for the majority of the season they would definitely be in the top 10.

Manchester City were pretty impressive tonight, with both David Silva and Samir Nasri linking up well and Sergio Aguero starting to look like his old self again. Of their 14 shots on goal tonight, eight were on target. Not a bad conversion rate.

Brede Hangeland header again! What a save from Tim Krul, superb from the Dutchman to deny Palace a second goal.

Everton boss Roberto Martinez calls defeat 'really hard to take' and calls Gareth Barry's red card 'very harsh'.

Full reaction to come from all of tonight's games.

A sophisticated stalemate.

Palace attack brightly again but Fraizer Campbell takes a wrong turn and ends up down a cul-de-sac. Is there a winner in this one?

"If Burnley perform like that every week their survival is possible. They work ever so hard as a team, they understand each other's games. But the same old frailties are on show every week, and it always costs them."

Southampton had 21 shots on goal tonight, but only seven were on target. The Hammers chanced their arm four times, with Fraser Forster making just one save.

"Over the season so far Southampton have had the rub of the green, but tonight it just didn't run for Saints. They could not find that extra bit of magic, flair or imagination."

A very solid night for Dougie Freedman and co. Wigan - it's looking like League One.

Burnley can be proud of their effort tonight. They took the game to Manchester United, but just switched off at two set-pieces before that late penalty sealed the result. On the positive side though, I saw a poll today which said Burnley were the best looking team in the Premier League. Every cloud...

Big scenes of celebration from the Chelsea players at full-time, they know that last-minute goal could prove very important come May. What exactly happened with Gareth Barry? I'm not so sure - I'll try and see some replays now.
