Southampton have delved deep into their energy reserves but are pushing now as Eljero Elia watches his rising effort pushed over the bar. He stamps his feet in frustration, that could have been the chance.
Late drama! Jeffrey Schlupp sidefoots home a cross from eight yards. From 1-0 down to 2-1 up.
Reading look like they have won it right at the end as Welsh winger Hal Robson-Kanu buries one.
SEVEN MINUTES ADDED ON! Is this some sort of joke...?
Twenty-one players in the goalmouth as Chelsea throw the kitchen sink at Bradford. Like Balboa v Drago, they just stand there and take it...
As close as you can get to a goal! Frank Lampard from 20 yards, deflected - off the inside of the post and away!
Aidan Williams: Chelsea losing, Manchester City losing, script writers rooting for Gerrard?
Sergio Aguero into the box - cleared. Middlesbrough edging closer to glory...
As Bradford close in on one of the very best upsets I can even recall. To win at Stamford Bridge, Jose Mourinho's Bridge, is one thing. But to come from 2-0 down and still win? Ridiculous behaviour.
Bradford a few minutes away...
Almost for West Brom as Brown Ideye plays a delightful through ball to Chris Brunt, who can only watch his shot rattle the post.
Middlesbrough are moments away from a famous win - but they won't even be the biggest story of the day...
QPR goalkeeper Robert Green
Final score
"This is a very non-Mourinho-like performance from Chelsea. They don't go 2-0 up and throw it away. You would not even have got odds for this. You go to Chelsea just thinking about knocking five minutes off here, another five minutes there, you're just thinking about staying in the game."
Game, set and match. Will Hughes buries from a tight angle and that is the end of Chesterfield's fine display.
Hugo Rodallega smashes one against the post! 20 yards out, thumped against the post.
The story of the day is at Vicarage Road where Watford have come back from 2-0 down at half-time to lead Blackpool 7-2. Odio Igaho gets his fourth and Watford's seventh in this second half. Brentford have re-taken the lead away to Norwich. Alex Pritchard, on loan from Tottenham, scores from the spot to put them 2-1 up.
Mark Beedie:, external Unbelievable. That's what happens when you make nine changes. You got it wrong today Mourinho.
Into the last few moments and a chance for Chelsea! But Kurt Zouma blasts one way over...
Steve Claridge
Final Score
"It has felt like a game that could go either way, and Mourinho has been really animated. They have never looked comfortable since Stead scored, and Bradford are getting their just desserts."
Here's what Jose Mourinho said on Friday: "To help the title race, the best thing is to lose against Bradford and to lose against Liverpool and to lose against Paris St-Germain and to play only Premier League until the end of the season.
"But not with us. Not with our mentality, not with our way of thinking about our job, not with Chelsea DNA.
"The other day, a coach of a big team was knocked out of the cup and he was saying 'good, very good, this is perfect for us, now we can focus on the other competitions'.
"If I lose against Bradford I don't say that. I say it's a disgrace."
