The npower Championship side have looked resurgent under the guidance of Eddie Howe while West Ham languish in the Barclays Premier League relegation zone.

Carlisle is confident the Lancashire side have it within them to secure victory at Upton Park.

"There would be no point turning up to a game if you didn't have the belief you could win," Carlisle told Press Association Sport.

"And I think we have strong grounds for a belief. We are in good form at the minute, the squad is feeling confident.

"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.

"I think the biggest thing the gaffer has given us is direction.

"I felt we were a team that didn't know which way we wanted to go beforehand, but he has collared everyone and said, 'This is the way we are going'.

"He said, 'We're going to do things this way and you're either in or you're out' - and that is what I believe this squad needed.

"Let's hope everybody buys into it fully to make us successful."

With such confidence in the camp, the who famously made a guest appearance on the BBC's Question Time last month believes a tilt at promotion back to the Premier League at the first attempt is still achievable.

"It has never been out of our sights," Carlisle said. "Even in our spell of sporadic form we have always been in and around the play-off picture.

"It's almost comforting to know you can be in bad form and still be up and among the leaders, so we're just excited at what we can achieve when we're in good form."
