And that just about wraps things up, on what's been an unforgettable night if you follow Salford Red Devils.

They will be featuring in Super League's showpiece for the first time, with St Helens standing between them and one of the most unlikely title wins in the sport's history.

We'll have live text and radio coverage of the Grand Final on 12 October.

Before that, on Saturday we'll discover which club will be heading up to Super League. Toronto or Featherstone for the top flight? Hope you can join us from 19:15 BST tomorrow to find out.

So Salford become the eighth club to reach a Super League Grand Final since it was introduced as the title decider in 1998.

Three seasons ago, Salford needed a golden-point drop-goal to secure their Super League status. They're now one win away from being champions. What a transformation.

More from Ian Watson:

"I think it breathes life into the competition and gives everybody a boost outside the normal top four or five.

"If you think about how many teams have been to or won a Grand Final, you can count them on one hand.

"For a club like Salford to go against the odds and get there, it gives people a hope that if you get good people in and you get a group that'll commit and buy into the things you want them to do, you can have success on the back of it."

Salford head coach Ian Watson told BBC Radio 5 Live Sports Extra:

"It's amazing. I'm delighted for the players. There are people in our club who probably never thought they'd grace a stage like Old Trafford or a Challenge Cup final ever again.

"With the adversity we've faced over the past four or five years, it's unbelievable."

Salford director Paul King tells BBC Radio 5 Live Sports Extra:

"It's a game-changer. In terms of prize money, interest levels and raising the profile - it'll make a phenomenal impact.

"It's incredibly surreal to be going at Old Trafford. I was there watching Manchester United there a couple of weeks ago. "I think our initial allocation is 8,500 and we'll sell those quickly."

BBC Two

Watch the best moments of tonight's game in a special highlights show on Sunday at 15:45 BST on BBC Two.

Might be a good watch for the Salford fans...

Salford prop Gil Dudson tells BBC Radio 5 Live Sports Extra:

"I'm lost for words. I couldn't have imagined this at the end of last season, getting relegated (with Widnes) and then Salford giving me the opportunity. To be in a Grand Final a year on is beyond my wildest dreams.

"My family's come up from South Wales for the game tonight and I think I'll have a few people messaging me asking for freebies for next weekend."

Salford centre Jake Bibby tells BBC Radio 5 Live Sports Extra:

"I can't sum it up. I'm lost for words. To turn a team like Wigan over 28-4 is madness.

"This bunch of lads have been amazing. We've been slated saying we were going to be relegated, and now look where we are. It's ridiculous."

Salford forward Josh Jones tells BBC Radio 5 Live Sports Extra:

"It's unreal. Look at those fans. It means so much to them and us.

"It was a tough game. Wigan are an outstanding team. We always thought we could do it and we've proved a lot of doubters wrong."

St Helens will be Salford's Grand Final opponents at Old Trafford on Saturday, 12 October.

Saints won 26 of their 29 regular-season games to run away with the League Leaders' Shield and will be overwhelming favourites to win.

But one thing we've learned - you never write off Salford Red Devils.

Reaction from the Salford camp to come, and remember you can listen to BBC Radio 5 Live Sports Extra coverage at the top of this page.

Amazing scenes of celebration at the Salford end. Jackson Hastings is in tears.

Salford have done it!

Wigan are on the front foot in the latter stages but there's no hope of a comeback.

Salford are just counting down the seconds until they can REALLY celebrate.

Warrington Wolves assistant coach on BBC Radio 5 Live Sports Extra

There's shell-shock around the place. I think both sets of fans believed their team could win and we all thought it could go either way.

It's the nature of the loss - you've never seen Wigan beaten so much in a play-off game.

It's now 50 points without reply for Salford in their past 150 minutes of play-off action.

Andrew Henderson
Warrington Wolves assistant coach on BBC Radio 5 Live Sports Extra

The challenge for Salford is to maintain this. I really hope off the back of this that they'll get some more investment and their fan base will start to grow.

If they go on to win it at Old Trafford, it will be brilliant for the game.

A lot of this Salford team are moving on to new clubs in 2020. Among them, Jackson Hastings and Jake Bibby will be joining Wigan next season.

Krisnan Inu kicks yet another penalty and it's 28-0.

Wigan fans look stunned in the stands. Salford fans are a different kind of stunned.

What a try! Wow.

This is an amazing performance. Absolutely amazing. That was great work there.

You can see the chemistry in this team.
