Didier Drogba's first goal of the season was not enough as shoot-out misery continues.

The Blues looked to be on the way to the quarter-finals after taking a first-half lead but the Championship side equalised midway through the second-half to take the game to extra time, played by Chelsea with 10 men due to injury.

When it came to penalties, Wayne Bridge missed but then Burnley fluffed their fifth kick. However Mikel saw his effort saved in sudden death.

As promised prior to the game, over half the side was changed from the Blackburn match with Mineiro receiving his first start in a Brazilian flavoured-midfield. Belletti and Deco were ahead of him and Kalou and Malouda out wide.

Bridge was captain for the first time with Alex and Ivanovic a new central defensive partnership and Drogba was back up front. There were the reassuring figures of Terry (not starting for the first time this season) and Lampard on the bench.

Belletti, from distance, was the first on the park to get a proper shot away. It flew well over. Then a minute later, with five on the clock, Ferreira found Deco in space with a searching deep cross but the header down was beyond Kalou's reach.

On 11 minutes, Bridge had a dig that bounced not too far wide after a free-kick rebounded off the wall.

Burnley, as could only be expected, were willing workers, harrying Chelsea in possession and making a couple of manoeuvres into our box. Later in the half it took a well-positioned Drogba to block a threatening shot from Elliott.

Drogba, looking at his sharp, marauding best in the early stages was behind the clearest opening so far on 19 minutes, expertly turning a ball into Kalou's path who had raced onside beyond the defence. His move was to go past the keeper but with forward-stretched legs, Jensen dispossessed the younger of the two Ivorians involved.

There was danger at the other end when Alex and Belletti got sucked into the same challenge and former Man United winger Eagles broke away. It took good covering from Ferreira to give Cudicini the chance to gather.

On 25 minutes there was a Chelsea change. The plan had not been to involve Lampard so soon but an injury to Belletti made him the clear choice to come on.

The Burnley fans jeered but were swallowing hard within a minute as Lampard, with his first touch, brilliantly played the ball up to Drogba who turned inside the last defender Duff and placed his shot to the right of Jensen. A world class instant impact and a world class finish. Drogba was booked in the aftermath of the celebrations.

All was going well but the closest Chelsea came to a second in open play before the interval was when Kalou slipped the ball wide to Malouda whose shot was pushed back into the danger zone by Jensen, unfortunately not within Drogba's considerable range.

The Blues were playing with increasing authority in the latter part of the half and on the stroke of half-time, Malouda's low free-kick from out wide - Drogba having been fouled in front of the 6000 strong Burnley end - was played near post and Ivanovic stooped low to head up onto the crossbar.

There was a half-time sub by Scolari - Mikel on for Deco with Mineiro the one moving further forward.

The unlikely Ferreira had the first shot of the second half, spearing one high and wide into the Matthew Harding End from 30 yards.

Suddenly there were a couple of moments of concern for Chelsea. Drogba, losing the ball in the centre of circle, appeared to jar his leg and hobbled afterwards. Then Cudicini came for a dipping cross and missed.

The Blues survived the second of those incidents and soon our forward was moving freely once more. He was eventually replaced by Di Santo on 67 minutes with no sign of injury. But the tide was turning.

A minute later Burnley equalised. Eagles it was who broke through on the left and hit an angled right-foot drive which Cudicini did well to stop with one arm. The ball was still alive though and fell to substitute Akinbiyi who finished powerfully from 15 yards. The scorer was booked for removing his shirt.

Eagles was booked for a foul on Mineiro on 72 minutes, his team-mate Caldwell punished with a yellow card for a foul on Drogba earlier on.

Chelsea, who were playing 4-3-3 with Kalou, Di Santo and Malouda up since the last substitution, began to fight back. Kalou headed over after Mikel had crafted a crossing opportunity past Blake.

Lampard did similarly on 86 minutes but this time Di Santo headed down and into Jensen's arms. They were misses the Blues would later regret enormously. 

Lampard drew a punched save out of the keeper a minute later with a free-kick from wide and in the follow up, Bridge shot over with his right foot from the edge of the area.

Di Santo had a speculative effort saved as Chelsea strove to avoid another 30 minutes. A gilt edged chance for a winner came to the teenage Argentine in stoppage time but from Malouda's pass, his first time shot flew disappointingly wide.

So extra time it was - and no remaining Chelsea subs to be used.

Lampard clipped the ball into the net two minutes after the restart but from an offside position and by then, there was a new problem for Scolari. Di Santo had emerged from a challenge holding the back of his leg and after a short examination, could not continue.

With 26 minutes to play, Chelsea were down to 10 men.

Lampard hit the outside of the post with an inswinging corner midway through the first period and scooped a shot well over when the ball was laid across the edge of the box. John Terry for one expected more as he rose to his feet from the bench before dropping down.

The midway point was reached with the lead still elusive. At least Burnley, save for a Mahon 30-yarder straight at Cudicini, had manufacture nothing in extra time.

The Lancastrians were first to press after the restart, Malouda sliding in to smother one attack.

Chelsea won two corners but still couldn't work Jensen and Burnley came strong again. This was worrying. There were several Chelsea players out there without too many games in their legs this season. Cudicini saved low down after a header skimmed off Akinbiyi.

However there was a great chance for Alex after Bridge returned an over-hit cross but off balance from six yards, he could only divert the ball over. Stamford Bridge groaned.

That was 24 minutes into extra time and a minute later the numbers were evened when Caldwell was dismissed for a second yellow after fouling Malouda. The free-kick from Lampard was spilled by Jensen but then grabbed amongst a forest of Chelsea legs.

The last shots were Mikel wide and an Alex free-kick too high. So Chelsea faced a penalty shoot out once more - and the chance to end a run of failure stretching back 10 years in competitive games to our last penalties success.

The end game would take place in front of the Matthew Harding End; Cudicini to face Alexander first. It went in off the underside of the bar. Close!

Lampard was next. Low to the left. No problem.

Mahon finished in the opposite corner to make it 2-1 Burnley.

Bridge then had his saved. It was low but aimed too central.

Eagles scored to make it 3-1 but Kalou finished confidently for 3-2 the visitors.

Next up was Burnley sub MacDonald who scored to Carlo's left.

Ferreira had to score to keep it going and did, high to the left - and then came the turning point. With the penalty to win it, Elliott's nerve deserted him and he blazed over.

Malouda, who also had to score, put it straight down the middle to level the score 4-4 and send it to sudden death.

Centre-back Duff scored so Mikel was next up. He struck his shot well enough but Jensen saved superbly with one hand for an almighty dose of déjà-vu.
