Steven Pressley says one of the worst FA Cup memories of his career is all the warning Carlisle United should need ahead of their trip to Dulwich Hamlet.

The Blues manager suffered an upset when his Coventry side were knocked out of the competition by Worcester in 2014.

Pressley says that should remind United not to take anything for granted against their non-league opponents tomorrow night.

He also admits Carlisle are to some degree heading into the unknown even though they have researched National League South side Dulwich thoroughly.

“I was at Coventry when we went out to Worcester and it was a real example to me just how dangerous this cup competition is, and you should never, ever underestimate any of the opposition in this competition,” Pressley said.

“That is a grave reminder to us of what the potential is on Friday night.

“We’ve watched quite a lot of footage [of Dulwich], but it’s hard to get a full grip on how they’ll play because when we watched Worcester in the run-up, they didn’t play particularly well prior to the game.

“They hadn’t been a team that really pressed the game, and they were the polar opposite in the game.

“The thing I took from it is that you can scout these teams as much as you want prior to the game but they’re a different animal on the day, especially live on TV. We have to be absolutely maxing out on Friday night for us to win the game.

“I expect Dulwich to press us, play with high energy, put the ball on top of us, ask all of these questions of us that we have to answer.

“But on top of that we have to impose what we’re good at on the game. That’s a really important aspect – yes, we do the bread and butter really well, but also we don’t lose sight of what we are as a team.”

Dulwich’s league form has been poor recently as they sit 16th in their division, whilst Carlisle are 19th in League Two.

Pressley, though, feels league exploits will be “no factor at all” on the sell-out game at Champion Hill, which is being shown live on BBC Two.

“I think you’ll see a Dulwich team that’s playing without any fear, and full commitment in front of the TV cameras,” he said. “It will be a high-energy performance from them.”

While neutrals will be hoping for an upset, Pressley says he accepts the extra pressure that comes with the presence of the TV cameras and United’s status as favourites.

“That’s part of being at this club – the expectation levels,” he said. “It’s part of playing against teams in the lower leagues. You have to win these games, we have to handle those types of pressures, that’s why this cup competition is such an exciting one.

“We’re really looking forward to the game. We’re under no illusions just how difficult a game it is. It’s probably one of the reasons it’s one of the live fixtures is everybody wants to see cup upsets.

“We’ve got to ensure we don’t fall foul of that. They’re huge banana skins. Dulwich have a very experienced squad with a lot of league experience. Make no mistake, it’s a difficult game.

“They’ve got a good set-up. It’s a small ground, not the biggest of pitches, they get a terrific support, a very vocal support, it will be a really good atmosphere, it’s got the makings of a great cup tie.”

He added: “It’s not often this club plays live on national TV. It should be really exciting for our players and supporters.”
