For more than two decades, Nottingham Forest have been out of the top flight, despite being present in top-flight football from the late 1970s to the early 90s.
They could be on the verge of a comeback, which was not anticipated at the start of the season.
Ahead of the Championship play-off final on Sunday, the BBC asked Forest fans how they were feeling.
The last time Neil Heath was there, Wembley looked very different.
"This will be my fifth time with Forest at Wembley, but my first at the new Wembley," said Mr Heath, from Arnold, a City Ground regular for many years.
He said that the stadium was his team's second home for a long time.
We were there six times between 1989 and 1992 and I remember saying to my dad, "We get to Wembley every year, don't we?"
He said that he told him to just make the most of it.
There has been a 30-year gap. I didn't think that would happen when I was a kid.
They were one of the best English teams and used to finish third. Nowadays, that would be a top league.
The return to Wembley was particularly special for fans of his age who have not seen them in a while.
He said that returning to the top flight would be incredible for someone of his generation.
People younger than me are excited because they have never experienced anything like this before.
He said that this season has seen fans unite behind manager Steve Cooper, who took over in September after a seemingly endless succession of hirings and firings.
He said that Steve Cooper has something that Cloughie had - he has united the players, their families and the fans.
No matter what happens on Sunday, it has been an incredible achievement.
Being a Forest fan has been like being trapped in a bad marriage.
You love them so much that you can't leave them.
It has hurt a lot over the past few years, but now fans can really get behind the team, and a club like Forest needs its fans.
One of the fans who has never seen their team in the league is Max.
He said that this season has been his best ever as a Forest supporter.
It's nice to hear about history and the remarkable things we achieved, but we need to create our own success for young fans. This is why this is so big.
A man who lives in Staffordshire but has a family from Nottinghamshire has 8,000 followers on his YouTube channel.
He said that he set it up when he was 13.
He will be travelling with his family to Wembley.
The family is Forest season ticket holders.
This is huge for us. He said that we are one step away from the premier league and anything could happen.
It is going to be a nervous 90 minutes.
Ben Neil has been a season ticket holder for a long time.
When Mr Neil, who has Type 1 diabetes, had two below- knee amputations in quick succession after suffering years of health problems, he wanted to walk to his seat in the first home match of the season.
He said that Forest asked him if he would like to walk on to the pitch for the first home game of the season.
I did it in front of 20,000 people with my wife at my side. It was one of the best days of my life.
I will be going to Wembley with Kirsty. Hopefully she will see us getting promoted and it will be as if things have come full circle.
Mr Neil said he felt inspired by Forest this season.
It has not been that great the past few seasons, but this year is something special, said Mr Neil, originally from Newark.
It is almost as if the stars have aligned. It almost caught people off guard.
It was always going to work out with the amount of managers we have gone through.
It would mean a lot after years of pain. A club of Forest's size should be in the premier league.
Sam Perkins is going to Wembley with friends, family and his two full-time carers.
He said that they have been with him at all of the home matches.
At the age of 37, Mr Perkins was diagnosed with motor neurone disease.
He used to follow Forest home and away, but now focuses on the simpler journey from his East Leake home to the City Ground with his electric wheelchair, cough assist and ventilator, which he uses 24 hours a day.
I was told that 50% of people who were diagnosed pass away two years later. He said that he tries to make the most of every day.
Mr Perkins and his wife Emma have set up a charity called Stand Against MND, which has raised over one hundred thousand dollars for research and care for people with the disease.
He said it was nice of Forest to give him something positive. At the start of the season, I didn't think we would go to Wembley and the premier league.
It is a huge surprise. Forest has taken me to other places but never to Wembley.
Bal Bansal said he would be driving with his son to Wembley.
He said that he knew where he was going.
I think the nerves will kick in at 16:30 BST on Sunday, but I am just about managing to sleep.
Mr Bansal, an IT worker from West Bridgford, traveled to watch Forest play Spurs at the previous Wembley stadium but said recent visits had been sparse.
I remember the late 80s and 90s but the only time I have been to Wembley in the last few years was to watch Eminem perform.
It is going to be a great day for me.
I would love if we win and are promoted. It will be fun to play in the premier league again.
We wanted to play them so that they could stay up.
The game has become more diverse since the last time Forest were in the premier league, according to Mr Bansal.
If you go back to the 80s and 90s, you wouldn't have many black and Asian people going to the matches.
Nowadays, you have all these different supporter groups and fans travelling to games from around the world, which is great. It encourages more people to go.
