After knocking London-based Premiership teams Fulham, Chelsea and Arsenal out of the Carling Cup, Burnley will be aiming to increase their capital returns when they visit Tottenham Hotspur for the first leg of their semi-final on Tuesday evening.
And manager Owen Coyle, whose team are chasing promotion from the Coca-Cola Championship as well as Carling Cup glory, says the Clarets will be going out in positive fashion to produce another shock when they step out at White Hart Lane.
The Burnley boss said: "If you are negative in any way they'll pick you off, so we'll commit players forward to make a real game of it. I want us to be brave in possession and show the things that have brought us to this stage.
"We know Tottenham's quality, but we are there on merit and we want the chance of another big day. If we're still in the tie coming back to Turf Moor it will be a decent result - what I don't want over the two legs is for my players to have any regrets."
Coyle is a big admirer of his opposite number Harry Redknapp, but having already outwitted Premiership managers Arsene Wenger, Luiz Felipe Scolari and Roy Hodgson, the former St Johnstone boss is keen to claim another top scalp.
"You want to pit yourself against the best," said Coyle, "whether it's as a player or as a manager. Harry Redknapp is an inspiration to any young manager, but obviously I want us to come out on top as we did against those other big clubs."
Tottenham sprung a surprise by beating Chelsea in last year's final under previous boss Juande Ramos. Meanwhile Redknapp, as Portsmouth manager, led his previous team to FA Cup glory with a Wembley final victory over Championship club Cardiff City.
Now he is hoping to lead Spurs out at the national stadium, but he is taking Burnley's threat seriously as he prepares for the first leg. "They've had a fantastic run and so we certainly won't be underestimating them," he said.
"I watched them on Saturday against QPR (in the FA Cup) and they are a well organised team with experienced players," added Redknapp, whose own team line-up will be affected by injuries and suspensions.
Darren Bent and Tom Huddlestone have failed to recover from injuries, captain Ledley King will not be risked because of his continuing knee problem and both Benoit Assou-Ekotto and Jermaine Jenas are suspended.
Add to that the fact that Redknapp's men have collected just two points from their past four Premiership games and sit above the relegation zone only on goal difference, and they could be vulnerable against the Championship's fifth in the table team.
Burnley winger Robbie Blake, a goalscorer when the Clarets beat Spurs 2-1 in the League Cup at Turf Moor in November 2002, reckons that another shock could be in store. He said: "It's been unbelievable, the teams we've beaten to get here.
"Now we need one last big push to hopefully reach the final. If they play well over the two legs they'll be favourites to go through, but we've caused upsets against Chelsea and Arsenal and we're capable of doing it again."
