94th min: Full whistle has blown and Derby County have lost 3-1 to Chelsea. The blues will go into the draw for the semi finals and they will be joined with Sheffield United who surprisingly took down Southampton 1-0. Bournemouth and Liverpool, and Tottenham and Newcastle will the second batch of quarter final fixtures tomorrow.
93nd min: Clever build up play finds its way to Chris Martin who shoots just wide from the edge of the box.
Go from bad to worse for Southampton. 1-0 down they have now lost a player, Florin Gardos sent off. Four minutes injury time left.
84th min: Eden Hazard off for Ramires.
83rd min: Derby County make a last change as Mascarell comes off for Leon Best. It is a statement of intent to go down kicking and screaming as a striker comes on for a midfielder.
81st min: GOAL! Game over as Schurrle adds a Chelsea third. Fabregas slid in Remy whose shot could not be saved and Schurrle pounced on the rebound.
77th min: RED CARD! Controversial red card as Jamie Buxton is sent off for being the last man for fouling Loic Remy. In reality Lee Camp got to the ball before Remy did so it wasn't a goalscoring opportunity.
76th min: Derby make another sub as Will Hughes is off for Hendrick.
74th min: Jordon Ibe has made a great impact on the game. He had a big impact in the first and now he has dribbled past Azpilicueta and Ivanovic with ease before having to settle for a corner.
70th min: GOAL! Terrible, terrible, terrible mistake from Ivanovic allows Craig Bryson to score. Ivanovic cleared the ball straight to Bryson who passed to Russell. Russell made an inward run from the right wing and played it back to an advanced Bryson who placed the ball into the bottom left corner from outside the box.
63rd min: Didier Drogba comes on for Loic Remy.
57th min: Jordon Ibe comes on for Dawkins as Derby look for fresh impetus.
Southampton have gone a goal behind to Sheffield United courtesy of a Marc McNulty goal. Tough times for the south coast club after a great start to the season.
55th min: GOAL! He's had a fantastic game and he has capped it with a goal. Filipe Luis curled in his first Chelsea goal from long range free-kick. 2-0 Chelsea.
It's gone past the hour mark in the other Capital One Cup quarter final and it is 0-0 between Sheffield United and an out-of-form Southampton.
53rd min: Didier Drogba is fuming with Schurrle. It was great combination play from Filipe Luis and Hazard to create the chance for Schurrle. However, his angle for goal was narrow and he should have squared it for Drogba. He didn't and his shot rolled harmlessly wide.
51st min: Better from Derby, much better. Russell skips past John Terry and leaves him a heap on the floor. His cross on the right finds Will Hughes free inside the box, though his shot is well saved by Cech for a corner.
46th min: Derby get their first effort on goal and it was a tame one. Mascarell's free-kick looped over its intended target and dipped nicely into Cech's arms.

Well, that 1st half will be forgotten in a hurry. Derby County kept Chelsea honest but for a slight mistake which was duly punished by Eden Hazard. There is some concern over Kurt Zouma who sustained a nasty injury.
52nd min: Referee blows for the end of the 1st half.
48th min: After some confusing, Ivanovic has indeed now replaced Zouma. Hopefully it is nothing serious, although he was reported to have been bleeding from the mouth.
44th min: Branislav Ivanovic is lining up on the touchline and appears to be the man to replace Kurt Zouma who is still laid out on the floor, assuming he cannot play any longer.
41st min: Three successive Derby County corners come to nought as Petr Cech clatters Kurt Zouma in the head. It looks quite nasty and the referee rightfully stops play so the defender can receive treatment.
28th min: Fabregas is really running the show now. His lobbed through ball falls between Drogba and Buxton, with Buxton managing a last ditch block.
27th: Cesc Fabregas puts the overlapping Filipe Luis in on goal on the left flank and the defender's shot stings the gloves of Lee Grant. The ball trickles out for a throw-in.
22nd min: GOAL! I was just about to praise Derby County until Keogh made a gaff. His poor clearance was intercepted by Eden Hazard. The rebound fell to Cesc Fabregas who played it back to Hazard. The tricky winger simply waited for the slightest opening then slotted the ball into the net.
8th min: John Obi Mikel puts Drogba in goal but the striker fails to hit the target.
3rd min: First yellow card of the game and it falls to Andre Schurrle. The winger commits a professional foul after Johnny Russell knocked it past him.
2nd min: Filipe Luis whips in a cross and Didier Drogba gets a head to it. Unfortunately a Derby defender blocks it.
