A Heidar Helguson penalty saw QPR beat nine men Chelsea and claim the West London derby spoils at Loftus Road.

The Icelander netted from the spot in the tenth minute after he was awarded a penalty following contact from Chelsea's David Luiz in the box.

The Blues were then reduced to ten men on 33 minutes when Jose Bosingwa received his marching orders for fouling Shaun Wright-Phillips.

And things went for bad to worse for Andre Villas-Boas' side when Didier Drogba was dismissed for a two-footed challenge on Adel Taarabt four minutes before the interval.

In the second period, Luiz thought he should have won a penalty off Helguson and Nicolas Anelka headed straight at Paddy Kenny from close range as the Hoops held on to inflict a second league defeat on the third-placed Blues and move into the top half of the table.

The defeat saw Chelsea - who, as well as the two sending offs, received seven yellow cards - blow the chance to capitalise on Manchester United's derby humiliation and move second in the Premier League, while also leaving them six points adrift of leaders Manchester City.

That merely added to the jubilation for the home fans as they celebrated their side's first home victory since promotion - and a first win over their arch-rivals for 16 years.

Captain Joey Barton's personal attack on opposite number John Terry six days earlier did not prevent the pair shaking hands before kick-off but there was no love lost between the rival fans in what was a cracking atmosphere at Loftus Road.

Daniel Sturridge and Luiz threatened early on but the latter's habit of making daft challenges cost Chelsea dear in the eighth minute when they failed to deal with a long clearance and the defender needlessly nudged Helguson over in the box.

Referee Chris Foy pointed to the spot and Helguson snatched the ball from a far-from impressed Taraabt and sent the penalty into the top corner via Petr Cech's fingertips.

Bossing possession

The Blues were bossing possession without creating anything of note and their afternoon took another turn for the worse in the 33rd minute when Bosingwa was controversially sent off.

Bosingwa hauled down Wright-Phillips when the winger threatened to burst clear, with Foy deeming the right-back to be last man and brandishing red.

Chelsea were livid with the decision, which was followed by Taraabt curling the resultant free-kick too close to Cech.

Blues boss Villas-Boas sacrificed Sturridge for Branislav Ivanovic but his misery was far from over, with Drogba getting himself sent off four minutes before half-time.

The striker lunged in two footed on Taraabt and left Foy with little option.

Villas-Boas took action again in first-half stoppage-time, withdrawing Mata for striker Anelka.

It looked a lost cause for the nine men, who were sent out a full two minutes before their opponents after the break.

Incredibly, they went close to levelling straight away when Lampard was just beaten to Raul Meireles' brilliant cross.

Kenny also flapped at a dangerous Ivanovic ball but they were soon hit on the break and John Obi Mikel was booked for upending Taraabt.

Lampard and Shaun Derry had to be dragged away from each other following a penalty-box scramble, with Foy booking both.

Great chance

Luke Young screwed a great chance wide as Rangers finally began to make their advantage tell, while Ivanovic became the latest man cautioned for clattering Taraabt.

Barton picked up a yellow for going in late on Terry before Taraabt was withdrawn for Tommy Smith on the hour mark, the Moroccan living up to his reputation for storming down the tunnel.

Young got in behind again five minutes later but he drilled his cross straight at Cech.

Lampard was furious midway through the half when he felt Fitz Hall had bundled him over in the box only to see the officials unmoved.

Luiz was booked for another poor challenge before seeing a penalty appeal turned down when he hit the deck under challenge from Helguson.

Barton almost scored on the break, and Meireles was booked for dissent before being immediately withdrawn for Florent Malouda.

But there was no stopping the yellow tide, Cole picked up a suspension for his fifth booking of the season and was almost made to pay for his booking when Helguson volleyed over from point-blank range.

But Chelsea should have capitalised with just over 10 minutes left when Ivanovic put the ball on a plate for Anelka, who somehow headed the ball straight at Kenny from four yards.

Jamie Mackie replaced Derry but Chelsea wasted another great chance to level when Lampard deflected Luiz's overhead kick over the crossbar.

With time running out, Villas-Boas made his feelings clear to the fourth official, while tempers flared late on when Terry closed down Kenny and the pair squared up on the six-yard line.

There was still time for Cole to nod a weak header at Kenny and Cech - of all people - nearly to get his head on the end of a free-kick.
