Carlisle eyes Upton Park upset
Clarke Carlisle insists Burnley have the attitude and aptitude required to cause an FA Cup upset at West Ham.
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."
