Dons assistant manager Gary Waddock was pleased to have avoided the potential FA Cup banana skin that was Halifax Town.
The 4-1 victory saw Dons passed safely into the second round, with two goals from Izale McLeod, a Shaun Williams penalty and a late strike from Brandan Galloway.
McLeod’s first strike, a peach from the edge of the area, came at a vital time, with six minutes to go before half time, to put Dons ahead at the break.
Waddock said: “The first goal is always important and it was a fantastic goal from Izale. It settled everybody’s nerves.
“They’re always difficult ties, because everyone expects you to come out and win comfortably.
“You’ve got to give credit to Halifax for the way they went about their game, but the most important thing is that we’re in the next round.
“We wanted to keep a clean sheet and build on last week, but you have to give Halifax credit and they didn’t stop. They’ll go away pleased with that, but defensively we should have done better. I thought their performance was very good.
“But we’re in the next round - job done.”
Waddock praised striker McLeod, who netted his fourth and fifth goals in his second spell at Dons, but made his first home start of the season against the Skrill Premier side.
“I’m pleased for him because this season he has been on the sidelines in the main, but when he’s come on he’s done everything right,” said Waddock. “And today, he’s got his reward. It was an excellent strike, and for his second, he was in the right place at the right time.”
Galloway’s injury time goal, his first in professional football, showed a cool head on young shoulders, and Waddock believes that while much of the attention has been on team-mate Dele Alli this season, Galloway has the ability to go far.
He said: “Brandan has had a decent couple of months. He’s been away with England and done really well, and come on here and scored. He’s a talented player.
“He’s been under the radar, but all the focus has been on Dele Alli - and rightly so because he’s a very talented boy.
“But his performances have shown how good a player he is. He’s got on with his work and who knows? If he can get a few more minutes under his belt, next year he could really kick on.
“But looking at the line-up, there are seven who are under 23. It bodes well for the future.”
