BURNLEY were given a taste of their own medicine in this Carling Cup shocker.

The Clarets have enjoyed some memorable cup upsets in recent years, humbling Aston Villa in 2004 and famously dumping Liverpool out of the FA Cup later that season.

But it was lowly League Two side Hartlepool United who undertook the giant-killing role at Turf Moor last night and, like Accrington Stanley's the night before, their fans celebrated wildly on the final whistle, as their side booked their place in the next round.

For Steve Cotterill it was an embarrassing defeat, his side's second poor performance at home and his side's second defeat on the spin.

The visitors record wasn't something to strike fear into Cotterill's side - lost two, drawn two, scored one goal in six hours of football and conceded four.

But they frustrated the Clarets for the entire 90 minutes.

The dour match looked to be heading to extra time before Wayne Thomas brought down Joel Porter .

Hartlepool have had three spot kicks awarded to them in their opening four games - and missed them all.

Fortunately, Porter wasn't in the mood to make it four misses and he scored, only to be ordered to take it again.

But he held his nerve to bag the winning goal.

Cotterill made three changes from Saturday's disappointing defeat to Wolves, bringing in James O'Connor, Steve Foster and Andy Gray, who returned from suspension; with Frank Sinclair, Micah Hyde and Wade Elliott relegated to the bench.

It was an attacking line-up from the Clarets but after a frantic start it was the visitors who almost opened the scoring.

Antony Sweeney stood the ball up at the back post for Eifion Williams who was unmarked but the striker volleyed just wide.

It was the wake-up call Burnley needed but for all their possession they couldn't find a way through the Hartlepool defence.

And it took until the 34th minute before they enjoyed their first real effort on goal when Andy Gray flicked a header into the path of teenager Kyle Lafferty but the youngster's shot flew high and wide and didn't trouble Demi Konstantopoulos.

At the other end Foster, making his first start for the Clarets, gifted Matt Robson a sight of goal but his shot trundled wide of the right hand post.

Burnley were huffing and puffing and the home support were beginning to get restless.

Gray chested down again for James O'Connor but his poor shot was typical of the poor half Burnley were having.

Cotterill must have had plenty to say at the interval with Hartlepool forced to wait several minutes before the Clarets arrived back onto the pitch.

And his words almost paid dividends when Steve Jones fizzed in a cross-cum-shot that flew just wide.

Hartlepool even gave the Clarets a helping hand when Gary Liddell miscued a clearance over his bar after a cross from O'Connor was flicked on by Jones.

Hartlepool, however, were enjoying their best spell of the match. John Brackstone's free kick on the hour mark was blocked by the wall and Eifion Williams pounced on the rebound but his shot cannoned off Michael Duff for a corner.

Jones tried to grab the game by the scruff of the neck and burst free from the touchline but his 30-yard effort was always sailing wide.

Foster teased the Pools defence with a couple of crosses and Wayne Thomas powered a header from a corner but still there was no way through.

But with just 13 minutes to go Thomas suffered his moment of madness, letting a long ball bounce in front of him where little Joel Porter was waiting.

Porter took the ball on, skipped past Duff and with just Jensen to beat the Clarets captain desperately lunged and brought him down leaving the referee with no other choice but to point to the spot and send thomas for an early bath.

Porter dusted himself off and, despite missing a penalty after two minutes in the first game of the season he scored - not once but twice when the referee spotted an infringement and ordered a retake.

The Clarets almost levelled minutes later when Andy Gray met a Wade Elliott cross but Pools 'keeper Konstantopoulos acrobatically tipped the ball over the bar.

And in the end it was too little too late as Hartlepool fans celebrated their first win of the season.

For the Burnley team and fans, they can only dream of what might have been on a very disappointing night at Turf Moor.
