The Chesterfield youth team will travel to Leicester City on Monday, January 19 in the fourth round of this season's FA Youth Cup.
The fixture, which will kick-off at 7pm, was finalised after an own goal from Wigan Athletic's Sean Harrison gave the Foxes a slender 1-0 win in the third round match on Wednesday evening.
Chesterfield qualified for the fourth round themselves after recovering from a two-goal deficit to record an almighty giant-killing in beating Aston Villa 3-2 on Monday night at the Proact Stadium.
Having navigated his own side's route into the next round, Smith was at the Leicester-Wigan match.
He said: "I feel that Leicester are beatable, we would have to be at our best to have a chance and they'd need to be a little under par.
"However, I thought that there are weaknesses in their team that we can try and exploit and that's what we'll be trying to do. We'll go there now full of confidence."
With the next round taking place at Leicester's King Power Stadium, Smith took a number of his youth team players along to the match to see what lies in wait for them.
He said: "The idea was that they get to have a look at the ground, which is quite impressive, then get a look at the opponents that they'll be up against.
"I think they took enough notice to see that the team they'll be up against are probably not unbeatable."
Away fans will be welcomed to travel to the King Power Stadium on the day to support the young Spireites in their fourth round match.
