Hartlepool United manager Ronnie Moore says his side have been given a warning by Salford City after seeing them knock out Notts County in the FA Cup.
League Two Pools face Northern Premier League Premier Division part-timers Salford in the second round on Friday.
"We've had the warning, we've seen what can be done - Notts County didn't," Moore, 62, told BBC Tees.
"We know what to expect, we've got to go and roll up our sleeves. There's no easy place to go in the FA Cup."
Moore took over at Victoria Park last season after Hartlepool were beaten by non-league side Blyth Spartans at the same stage of the competition, something he wants to avoid against Salford.
"It'll be a really tough game, they're at home and I think every person in the country wants us to be beaten so we're fighting the nation - except everybody in Hartlepool," he added.
"Around the country they all want the giant-killing act and that's basically what this cup is like, and if we go in with the same frame of mind as Notts County then there's only one outcome."
Moore insists his players will not feel pressured by playing Salford City despite them being owned by Manchester United's 'Class of 92', quintet Ryan Giggs, Paul Scholes, Nicky Butt and brothers Phil and Gary Neville.
"It doesn't matter who is there," said Moore. "The 'Class of 92' can't play. They might be there watching but they can't influence the game so there should be no fear factor about the Nevilles and the Manchester United connection.
"We're playing Salford City, that's what you've got to remember and we've got to show them respect and what a good side we can be."
