Bolton Wanderers boss Steven Schumacher told BBC Radio Manchester:
"I couldn't think of anyone better to score that goal to take us to Wembley. It has been tough for Xav this season. He has found himself out of the starting XI, sometimes out of matchday squads, but he is a model pro.
"It wasn't an easy game. We knew it was going to be difficult coming here, the intensity that was going to be around the game, the crowd, the atmosphere.
"I thought we played OK in the first half. I felt we were slightly on top, but in the second half we didn't pass the ball well enough. We didn't have any control in the game. Every time we did turn the ball over, we gave it away, and they put us under loads of pressure.
"We needed Jack to make a couple of brilliant saves, which he did, but you need your goalkeeper in big games like this.
"I'm so pleased, and for us to get the second goal after they had one disallowed was a killer blow for them and we saw the game out well.
"I was trying my best to stay as calm as possible and try and help the players through in what was a tough game but it's not easy. It was hard trying to get information out, it was so loud.
"I'm just glad that we've kept another clean sheet. To keep two clean sheets against Bradford in the play-offs is really good. It took a whole team effort for that and it's got us to Wembley."
