There it is, the equaliser! They've had to soak up a bit of pressure but Leicester have had their chances and finally make one count as Marc Albrighton's corner finds Jeffrey Schlupp, whose shot is blocked and Leonardo Ulloa sweeps into the bottom corner.

Preston are back on the front foot as this game enters its tense closing stages, Paul Gallagher forcing a good save out of Mark Howard after the away side failed to repel a cross into the area.

What a goal! What a goal!

Bradford City have come from 2-0 down to LEAD at Stamford Bridge. Amazing stuff. And it's a brilliant goal too, Jon Stead holding it up and laying the ball back for Andy Halliday, who runs on toit and thumps into the top corner from 18 yards. You don't save those.

What on earth is happening here...?

Manchester City didn't want a replay 90 minutes ago, they'd snap your hand off for one now. It's not happening for them in front of goal though, as Edin Dzeko comes on. Boro take off forward Lee Tomlin, who won't be able to sleep thinking about that chance if they don't hold on.

He smashed the post when it could have been 2-0...

Jose Mournho said it would be 'a disgrace' if his side lost today. What about a draw?

About 10 minutes left...

Shane Long, on as a substitute earlier, has to go off as he injures his arm after a nasty challenge by Joel Ward. Ronald Koeman won't be happy, he has already lost players to injury in cup games. Ryan Seager is on for his debut.

Final score

"No disrespect to Bradford, but Chelsea have to be winning this game. The quality is there for them to beat Bradford easily."

Eden Hazard is on for Chelsea, who can't have seen this one coming. A great weekend for the underdogs.

This game is being played at a furious pace. Moments after Tendayi Darikwa looks like going all the way for Chesterfield as he surges down the Derby right wing, the home side counter and Simon Dawkins hits the bar from a header.

Has Emmanuel Adebayor been forgiven for his slightly lacklustre display against Sheffield United in the League Cup in midweek? Judging by the reaction of the home fans as the striker comes on as a 70th minute sub for Roberto Soldado, the answer is a pretty definite no. Boos all round the stadium.

A hat-trick for Odion Ighalo at Vicarage Road. He is on hand to turn in after Troy Deeney hit the post for the second time in the game, and Watford now lead Blackpool 6-2. All of their six goals have been scored since the half-time break. Remarkable stuff.

Wow! There's the story! Bantams glory!

Brilliant stuff from the League One side as a long throw is launched on, Petr Cech does well to kick clear the first effort but it falls kindly for one-time Chelsea man Filipe Morais to convert from close range. Unreal scenes...

So close! Andrew Shinnie powers a header just over the bar for Birmingham. A collective "Oooooh" from the home crowd. This is edge of your seat stuff.

Cesc Fabregas whips in a cross and Didier Drogba plants a header at Ben Williams in the Bradford goal.

Alan Mackie:, external Middlesbrough should be 4-0 up in this second half. You can tell they're going to rue these misses.

Manchester City set up camp on the edge of the Middlesbrough penalty area but much like rivals United last night, their attacking players are hitting duff notes so far. David Silva pulls the red wall apart with a cracking pass but Sergio Aguero fluffs his shot.

Can Boro pull this off?

Paulinho comes within a whisker of doubling Spurs advantage, shooting wide of the post by a fraction after some wonderful build-up play by Erik Lamela.

Crystal Palace are looking tired and Southampton are the most likely to force an equaliser at the moment as James Ward-Prowse sees a shot blocked before Shane Long's effort is deflected wide.

Another chance goes begging for Derby, this time Jamie Ward fires wildly over the bar from a cut-back from Darren Bent on the right.

A further compliment to Bradford as Cesc Fabregas and Willian come on. The League One side continue to threaten and Jose Mourinho 's side need another goal.
