Clarke Carlisle insists Burnley have the attitude and aptitude required to cause an FA Cup upset at West Ham on Monday.
The npower Championship side have looked resurgent under the guidance of Eddie Howe, while West Ham languish in the Barclays Premier League relegation zone.
And Carlisle is confident the Lancashire side have it within them to secure victory at Upton Park, saying: "There would be no point turning up to a game if you didn't have the belief you could win. And I think we have strong grounds for a belief. We are in good form at the minute, the squad is feeling confident."
He added: "We have enough quality within our ranks to cause any team in the land a problem.
"We just need to make sure we produce that quality on the matchday and that defensively we're solid.
"If that happens, we'll be in with a fantastic shout."
Overall it has been a frustrating season for Burnley, whose indifferent form resulted in the departure of boss Brian Laws in December.
However, since former Bournemouth manager Howe arrived in mid-January, the Clarets have steadily risen up the Championship table and Carlisle acknowledges the 33-year-old's arrival has had a big impact.
"It is obviously giving the lads confidence and belief," he said.
"That shows in the run of form we're in and the way we have been able to churn out such good away performances, contrary to everyone's expectations."
