FIVE OF THE BEST... Carling Cup fifth round shocks

Manchester United 1-2 Crystal Palace The result of the Carling Cup so far this season without a doubt, as Crystal Palace headed to Manchester to dump the Premier League champions out before the semi-finals. Palace have been revitalised under new manager Dougie Freedman and looked a match for their hosts from the outset. But, it wasn't until the second half that the deadlock was broken - and it was a goal worthy of winning any game. Eagles substitute Darren Ambrose picked the ball up just inside the United half, surged forward and let fly with an absolute rocket that flew into the top corner. A clumsy Patrick McCarthy foul on Federico Macheda gave the Italian the chance to level it up from the penalty spot - but, the Championship side dusted themselves down. In the eighth minute of extra-time, Ambrose dipped in a free-kick and Glenn Murray was the hero as he nodded home the winner.

Burnley 2-0 Arsenal Back we go now to 2008, and a stunning victory for Burnley over Arsenal. Kevin McDonald was the two-goal hero for the home side that night as they made the Carling Cup semi-finals - where they were narrowly beaten by another North London team, Tottenham. A Lukasz Fabianski error gave McDonald the chance to open the scoring just six minutes into the game, and while the Gunners had many chances to equalise it just never came. The second was a curling shot early in the second-half and that was enough for the Clarets to progress at the expense of their Premier League rivals.

Blackburn 3-3 Chelsea The season after it was the turn of Burnley's most fierce rivals - Blackburn - to cause a Carling Cup shock. Chelsea were the visitors to Ewood Park in what turned out to be an epic encounter. It was the lively Nikola Kalinic who opened the scoring for the host, finishing off a neat move that involved Morten Gamst Pedersen and Pascal Chimbonda. Going in at the break one up was a fair reflection on the first-half, and led then Chelsea manager Carlo Ancelotti to make a triple substitution. One of those - Didier Drogba - had been on the field for just three minutes when he beat Ryan Nelsen in the air to head home the equaliser. Salomon Kalou then give the Blues the advantage before Kalinic headed home a Brett Emerton cross to level the scores. Kalou then had to leave the pitch through injury and, with the game going into extra-time, the Londoners played with 10. Benni McCarthy scored to give Rovers the lead in this time, but with the game heading to a close it was Paulo Ferreira who profited from a Paul Robinson flap to take the game to penalties. After David Hoilett scored for Blackburn, Gael Kakuta knew it was do or die - and he missed.

West Ham 4-0 Manchester United More disbelief than a shock possibly, as last year we saw a rampant West Ham demolish then holders Manchester United at Upton Park. Former United player Jonathan Spector and frontman Carlton Cole were both two-goal heroes for the Hammers as they turned on the style - it is well worth noting that Victor Obinna was also particularly impressive, and had a hand in all four goals. Spector sent the hosts in 2-0 to the good at the break after a header and close-range finish. The visitors were stunned, but it only got worse as Cole picked up his two goals with a header and a neat finish to seal a semi-final with eventual winners Birmingham City.

Cardiff City 2-0 Blackburn Rovers We've gone full circle, and ended up back at this season's competition - and it's another entry for Blackburn. The struggling Premier League side went to Championship high-flyers Cardiff - and were turned over. An Aron Gunnarsson through ball sent Kenny Miller away to open the scoring for the hosts, and it was the Welsh team who continued to do most of the pressing in the first-half. The 1-0 half-time scoreline was well deserved for the Welsh side, and they doubled the lead shortly after the interval. A Peter Whittingham corner saw Mark Bunn flap and Filip Kiss nodded home. From here, it was cruise control for the hosts as they set up a tie with Crystal Palace in an all-Championship Carling Cup semi-final.
