The Bit O'Red are set to make their first appearance in the final of the all-Ireland competition as they face Stephen Kenny's Lilywhites
The Bit O'Red boss is determined to prove doubters wrong when the two sides clash at Tallaght Stadium, in what will be the club's first appearance in the final of the all-Ireland competition.
"Going in as underdogs is fine," said Barcalough ahead of the game. "I love proving people wrong and winning against the odds in football."
Baraclough also believes that complacency could become an issue for Dundalk as favourites, suggesting that Stephen Kenny's side "might think they've a divine right to win a trophy" after their impressive campaign in 2013 and their positive start this season.
"Dundalk being slight favourites will have a good effect," added Baraclough. "That'll be unusual position for Sligo Rovers as our fans have been treated to some good years where we've won trophies.
"All of a sudden, maybe Dundalk might think they've a divine right to win a trophy."
The Sligo manager paid tribute to the fans that follow the team across the country and urged supporters to relish being in another cup final. "We’ve always had a good following," he said. "Even in league games and cup games. We've a massive Dublin following too who will be in full voice.
"Hopefully people will travel as you can’t take these occasions for granted, you never know when you're going to be in another cup final. This occasion will be no different."
Sligo Rovers head into the Setanta Sports Cup final with a clean bill of health. Kick off for the game is 16:00 BST.
