Candystripes boss admits that his side are up against the best team in the country as they prepare to take on Sligo Rovers in the quarter final of the cup
Speaking to BBC Sport, the Candystripes boss described the west coast club as the best team in the league but was also keen to emphasize his own side's capability of salvaging a result away from home.
The Brandywell club have won the EA Sports Cup a record 10 times and are the current holders, having defeated Cork City in the final at Turner's Cross last season. However, Devine believes that despite this history, his squad are firm underdogs.
"We're going to play what is probably the best team in the country at the minute," Devine told BBC Sport. "They have a fantastic squad of players, some of the best players that are in the league.
"They're at the top of the table with a big points advantage on the teams below them, so we're fully aware that it will be a difficult game."
He added: "But on the road this year, we've gone to difficult venues and gave a good account of ourselves, so it is important that we go into this game with a bit of confidence ourselves.
"We've already gone to the Showgrounds and we drew 1-1, live on television. I thought we played very well that night and we were unfortunate not to win it.
"But every game is different. We want to go there and do well. This is a trophy that means a lot to us."
Earlier in the season, Devine, who is in his first season of management, steered Derry City to the club's first ever Setanta Cup final, before losing on penalties to Crusaders.
The Belfast club knocked Ian Baraclough's men out in the semi-final of the competition, while they were also eliminated from the FAI Cup this season and Devine believes that there is extra pressure on Rovers to stay in this competition.
"It's very important for Sligo Rovers to win trophies this year," he said. "When you consider the amount of money that they've spent on bringing in top quality players I think that it is vital that they have some silverware to show for it."
He continued: "So, the fact that they have gone out of the FAI Cup, which they've won in the last two years, means that they have only got another two trophies to compete for and I'm sure that they'll be very determined to do well against us to stay in the cup."
Sligo Rovers host Derry City in the quarter final of the EA Sports Cup this evening, Tuesday June 26. Kick off 19:45 BST.
