Stevenage manager Graham Westley is out to make life as uncomfortable as possible for FA Cup opponents Reading.
League Two Borough have already famously seen off Newcastle at Broadhall Way and are ready to 'welcome' the Championship Royals to their modest ground as they attempt to make the fifth round for the first time in their history.
"This is not a nice place to come and everyone who comes here says it," said Westley.
"A big part of that is the environment and the pitch but the biggest part by far is the attitude of the players as they're a hungry bunch.
"We love playing in front of our own fans – every team does.
"The players are enjoying the confidence they've gained from proving to themselves just how good they are and any team with confidence becomes more dangerous.
"They are a dangerous bunch to play against, there's no doubt about, and we always enjoy our football and we work very hard at this place."
Leyton Orient are looking to spring another shock at Swansea, having already knocked out their Championship promotion rivals Norwich.
"It's a similar task to the previous round, but I'd say Swansea are probably a better footballing side than Norwich," said defender Terrell Forbes.
"They keep the ball well and the pitch is slicked up for them. But we'll go there, work hard and try to get the same kind of result."
Brighton manager Gus Poyet, who lifted the cup with Chelsea in 2000, has his sights set on another Championship scalp.
Having seen off Portsmouth in the third round, Poyet's League One leaders face a trip to Watford.
"It's a good test for us," said the Uruguayan.
"It's important that we keep seeing if we can compete against and possibly beat teams that are doing well in the Championship.
"The players will have a chance to show they are capable enough to compete against Championship sides because that will be important if we get promoted this season."
Crawley manager Steve Evans believes his side are capable of causing another upset.
The Red Devils travel to League Two Torquay in search of a place in the fifth round for the first time in the club's history and territory visited by only five non-league teams before.
Crawley have already defeated Swindon and Derby and Evans said: "There is no doubt in my mind we can win the match but then again we will need to be at our best. Our lads will be busting to play and I have belief in them."
