Wycombe manager Matt Bloomfield praised the professional attitude of his side as they defeated Wealdstone 2-0 at Grosvenor Vale.
A potential FA Cup banana skin was avoided with strikes by Beryly Lubala and Richard Kone proving the difference.
With the potential of a third-round clash with a Premier League giant looming, Bloomfield believed the League One leaders dealt with a difficult tie well.
He said “The fear at the start of the game was being the story of the day, live television and a big crowd are here.
“We wanted to make sure we conducted ourselves in the right manner, I spoke to the players about that this morning.
“We knew the threat Wealdstone would hold, there would be some awkward moments, and I think we dealt with the majority of that well.”
The hosts should have taken a 22nd minute lead when Alex Reid somehow put a Sam Ashford cross over the bar from under three yards out.
They were punished by an unstoppable Lubala free-kick six minutes later from a distance of 25 yards.
A second goal for the visitors came almost eight minutes after the restart, when keeper Jacob Adams scooped a Ryan Tafazolli header off the line.
The League One side made sure of their passage to the third round when a powerful solo run by sub Kone was finished with a fierce shot home.
Wealdstone manager Matt Taylor believed the quality of finishing proved to be the difference between the two sides.
He said: “You’re talking about tiny errors, good players at good clubs punish even the smallest of errors. We didn’t get the result but we got the performance.
“The first-half chance would have changed everything, the supporters were desperate to get behind the team.
“If the first goal had gone in you would have seen this place become quite intimidating. But it wasn’t to be.”
