Sule Sadiq: Actually starting to believe Arsenal can win the league. Come on Hull do us a favour and win.

Andrew Laing: What a comeback! On this performance Andrew Robertson will be signed by a bigger club in the Summer.. sorry Hull fans!

Robert Thompson: Based on performances so far, looks like Jones & Smalling could be starting at CB for England on Friday!

Second half under way.

Mike D, Wimbledon: After Steve Bruce's reference to Swan Lake what chance the game actually ends "tutu"?

So bad it's good...

Tony: The worrying thing from a neutral point of view is that Cahill is one of England's first choice defenders!

Jay, London: Cahill's uncertainty has has the effect of unsettling Ivanovic, with the result we've seen.

Simon, Glasgow: Am I watching Hull v Chelsea or a replay of Bradford v Chelsea?!

So what does this do for the league table as it stands?

Chelsea will be four points clear of Manchester City, with a game in hand. Hull would remain 15th but move four points clear of the bottom three.

Oscar Webster: Andrew Robertson having a great game so far! Fantastic crosser of the ball.

John Southworth: I have always respected Mourinho for letting players play their way out of bad form but surely Cahill needs a time out!

Imer Cardona: If Chelsea fail to win today, can we say that Man Utd are back in the title race? Maybe too optimistic but still a chance.

"Jose Mourinho must make a change at half-time and it has to be at centre-back. It won't be John Terry, but from the perspective of an England fan, it's not good news for Gary Cahill. Something has to change for Chelsea though as they are not dealing with the Hull approach so far."

Hull have had 14 shots to Chelsea's three; five on target to the Blues' two (both ending up in goals).

"We said at 2-0 this isn't over. It looked to me that Hull were playing well. Steve Bruce must have been completely confused to have been in that position. A great response followed. All the questions at half-time will be asked in the away dressing room."

James Wall: Jose needs to make 4 substitutions at half time. The worst defensive display I've ever seen.

Chris Batman: If Chelsea play this bad in every match for the rest of the season, Arsenal can go on and win the league!!

I won't pretend to have watched every Hull match this season but if they've had a better 45 minutes, I'd like to see it.

Hull are probably unlucky to not be leading at half-time and Gaston Ramirez has a shot blocked in the box.

Jose Mourinho goes down the tunnel early.

Two minutes of stoppage time. Gaston Ramirez takes the free-kick which is deflected over for a corner.

Chris White: For goodness sake Jose why are you playing Cahill over Zouma!? Poor decisions by him recently, sort it out.

Craig Jackson: Ivanovic going from goalscoring hero few weeks ago to defensive liability it seems for many fans.

Paul Cate: Black and orange comeback against Chelsea again.

It's another free-kick to Hull City and Branislav Ivanovic - who is having a poor game - absolutely barges into the back of Dame N'Doye, who was trying to take a high ball down on his chest with his back to goal.

Stupid free-kick to concede.

"I'm watching Branislav Ivanovic and I don't know what he's doing. He's falling down when there's nobody near him. He's having the strangest of afternoons and there's so many players out there you're asking questions about for Chelsea at the moment, the vast majority of them are at the back."

Hull's Gaston Ramirez gets the ball and sets off on a fantastic run, his first touch takes him past Gary Cahill and then he leaves Branislav Ivanovic on his backside but he drags his shot so horribly wide, it's hard to be certain it was a shot.

Mike in London: Costa's inability to respect a strong, fair challenge will always go against him. Whinging destroys his reputation, no matter how many he scores.

He is basically Didier Drogba in that aspect of his game.

Abel Hernandez flicks the ball up and Filipe Luis comes in with the most obvious handball you will see. The free-kick is whipped into the mixer and lands to David Meyler 25 yards from goal - his volley is optimistic to use a euphemism and well off target.

Hull midfielder David Meyler, who scored in that recent draw with Manchester City, controls the ball on the edge of the area but drags his shot wide. They've had eight shots to Chelsea's three so far.
