AFC Wimbledon boss Johnnie Jackson told BBC Radio 5 Live:
"It was an unbelievable goal from Josh, he got in behind, controlled it. It's a goal worthy to win any game, any tie.
"We probably should have made it a little more comfortable with some of the chances we had in the second half on the counter attack.
"But we knew 1-0 would be enough today, so that's brilliant."
On his players' achievement:
"They're such a great group of lads, they give everything for me, for the club, for the shirt - I can't ask for any more.
"If it hadn't gone our way today, it wouldn't have been through lack of effort or endeavour so I'm so pleased for them. They deserve their shot."
Notts County head coach Stuart Maynard told BBC Radio Nottingham:
"First and foremost, I'm devastated for the fans who were absolutely incredible today.
"On the game, it was very tough. I thought we started very bright on the edge of their box and we were camped in there quite a lot with a few efforts here and there.
"Then we conceded a very sloppy goal, and in these big games you just can't give a team of Wimbledon's quality at home, with their defensive record, a leg-up. That is what we have given them.
"Sometimes it's the type of goal you concede. We conceded a goal you shouldn't really concede, it's defensively poor from us as a group and it's frustrating.
"If he comes inside and puts one in the top corner, I think it's a different feeling and we come back. But it deflates you a little and goals change games.
"It made it a very up-hill battle. In the second half the frustration creeps in and I don't think we stick to the way we played in the first half, so it's frustrating."
