Tom Roberts wants “the right mentality to get the job done” as Holbeach United set off on the road to Wembley.
The Tigers’ dream of making the Buildbase FA Vase final will start on Saturday with a trip to lower-ranked Coventry Copsewood.
Holbeach were given an exemption to the first round proper after reaching the last 16 of the competition two seasons ago.
Despite three defeats in the league this month, the Tigers will be favourites to go into Monday’s draw for the second round to be played on November 12.
Coventry Copsewood have only won once in 11 games in the Midland League Division One this season but they knocked out Atherstone Town 2-1 in the FA Vase last month.
Tigers boss Roberts said: “You can’t look at the league tables. This is the first time they have got to the first round proper in the FA Vase so it’s going to be a big occasion for the club.

“They will make it a big game so we need to show the right mentality to get the job done.
“The competition is very important to us. It’s not just about making progress – we have to think about the bonus of financial rewards for the club as well.”
Holbeach could welcome back captain Jamie Stevens and striker Josh Ford while Stacy Cartwright’s fitness is being assessed.
However, they are without goalkeeper Rick Drury for the third successive game.
Roberts was unhappy that Drury, Stevens and Ford were all unavailable for Tuesday’s trip to Peterborough Sports who recorded their 11th win in a row in all competitions.
Roberts was also angered by the second-half red card for Matt Warfield when Sports were already 2-0 up.
He said: “I don’t think Warfield’s second booking should have been a free-kick.
“To send him off ruined the game as a spectacle.
“We had to change the system to 4-4-1 for damage limitation really.
“I thought the referee spoiled the game and we’ve also got to look at three key players who have gone away in the middle of October and missed games.
“We gave away two silly goals in the first half after almost going ahead but that was a great save to keep out Jordan Thomas’ shot.
“Then we conceded from a long throw-in soon afterwards and a soft penalty right on the stroke of half-time when he didn’t have to make a tackle.”
The first away league defeat leaves Holbeach 12 points behind the leaders.
Meanwhile, ex-Tigers players Lee Beeson, Kern Miller and Jake Duffy scored as Stamford – led by former Holbeach manager Graham Drury – won 3-2 at Wrexham to reach the Emirates FA Cup first round proper.
