The head coach’s claim comes as the League One leaders prepare for one of the biggest nights in the club’s recent history.
A sold-out Cardiff City Stadium will host the five-time winners, with a place in the semi-finals at stake and Barry-Murphy relishing the chance to test his young, attack-minded side against elite opposition.
The Bluebirds have already eliminated Premier League opponents en route to the last eight, most notably with a 2-1 victory away at Burnley, and their manager believes his squad will embrace the occasion rather than be intimidated by it.
Barry-Murphy, appointed in the summer following relegation from the Championship, has overseen a strong revival.
Cardiff sit top of League One with a four-point cushion, have won their last five league matches and are the division’s leading scorers, averaging close to two goals per game.
The progress has been underpinned by a clear attacking identity and faith in youth, with homegrown talents Dylan Lawlor, Isaak Davies, Joel Colwill and Ronan Kpakio all earning their first Wales caps this season.
While playmaker Rubin Colwill misses the Chelsea clash through injury, Kpakio is suspended and loanee Omari Kellyman is ineligible against his parent club, Barry-Murphy remains confident in the mindset of those available.
He said: “The biggest thing I learned from players in my career is that an occasion like tomorrow night was quite a daunting task.
“You think about the difficulties you may face, but these young players here have got no fear and attack every single situation.
“No matter what happens, the players will give every single thing they have for the club and come out the following day better players for it.”

The tie also carries personal significance for Barry-Murphy, who will be reunited with Chelsea head coach Enzo Maresca.
The pair worked together at Manchester City during the 2022-23 season when Maresca was part of Pep Guardiola’s first-team staff and Barry-Murphy led City’s Elite Development Squad and academy.
“He’s always been there for me and I’ve always felt his support,” Barry-Murphy said of Maresca.
“He had a big influence on the first-team squad when I was there. I always think with a manager of the calibre of Pep it can be hard to show what he showed.
“But he added bits of information or coaching points that helped the players, and the (fact) they relied on him so much was an insight into what he’s doing now.
“I have full admiration for him, but once you come to the games he’d be fully aware that we all try our best to compete.”
Barry-Murphy is also a familiar figure to several Chelsea players, having previously worked with Cole Palmer, Romeo Lavia and Liam Delap at City, Robert Sanchez during his time as Rochdale manager, and Facundo Buonanotte while coaching at Leicester City last season.
Despite the gulf in resources between the two clubs, Barry-Murphy believes the Carabao Cup offers the perfect platform for ambition and expression.
“The anticipation for the game since the draw was made has been everywhere,” he said.
“Luckily, we have tried to detach ourselves from that as much as possible whilst focusing on the league campaign, but now that it’s here, I think that the game is going to be incredibly exciting for everyone.”
He added: “For myself and the players, we still want to show ourselves in the best light and give a good account of ourselves when competing against a side who are the Club World Cup champions.
“We want to do our best and prepare properly for this game.
“It’s everything you want. We all have aspirations of testing ourselves against those at the highest level of the game.
“Every game that we have played in the competition, we have tried to be on the front foot as much as possible, and to show ourselves in the most positive light.
“It’s what the supporters want to see both away and at home. We will have to try to give those fans something to feel exhilarated by.”
For Cardiff, history shows they have beaten Chelsea twice before in the competition, in 1980 and 1986.
Barry-Murphy’s message is clear: regardless of reputation or occasion, his side will step out determined, fearless and ready to compete.
