Luton Town's pursuit of promotion encountered a major setback when Southampton lured away their cherished manager, Nathan Jones, earlier this season.
However, they have now reciprocated the favor by securing a place in the Premier League, replacing the south-coast club.
Jones had led Luton to automatic promotion from League Two and even a Championship playoff semifinal in two spells but left in November when they were ninth, leaving Luton in a predicament.
Enter Rob Edwards, the latest victim of Watford's managerial revolving door policy, and Luton had no qualms in handing the man who coached their rivals a three-and-a-half-year contract.
"Let's be honest ... if we avoided everyone with a connection to our adversaries, our choice would be somewhat more limited," club CEO Gary Sweet said.
The rest is history, as Luton finished third in the Championship and qualified for the playoffs on the back of a 14-match unbeaten run.
They saw off Sunderland in the semifinals after losing the first leg before beating Coventry City on penalties in a nerve-shredding final at Wembley to return to the top flight after 31 years.
"We (thought we) are in trouble because when we were taking some in practice, we were rubbish," Carlton Morris, Luton's top scorer this season, said.
"It's nice for all the boys to step up today. I said in our huddle that it is time to be men and step up. We scored six out of six penalties in a high-pressure situation."
Survival in the top flight would lead to a financial windfall of 290 million pounds ($366 million), according to Deloitte, but Edwards is keeping his feet firmly planted on the ground, saying they will be 'sensible.'
"We're not going to go mental. We have to play to our strengths," Edwards said.
"We realize it's going to be the biggest challenge ever. It's the best league with the best managers, the best players. We know how tough it is going to be.
"The fans have seen some dark, dark times. So it's great that we can smile at them."
Pelly-Ruddock Mpanzu had seen it all since he joined the club in 2014, training on a dog's field when he first arrived before the money came in through promotions and new facilities were built.
With 367 appearances for Luton, the 29-year-old is now the first man to go from non-league to the Premier League with one club.
"I've completed football; I'll retire this summer," he joked. "It's been a journey, through the highs and lows, but you've got to believe in yourself.
"Here I am, a Premier League player."
Kenilworth Road will be the smallest stadium in the top flight with a capacity of just over 10,300 - acceptable for when they were in the fifth tier a decade ago but not when competing with the Premier League's riches.
The club will be spending 10 million pounds on improvements before the new season kicks off in August, but the ground cozily nestled in the midst of terraced homes has its charm and could even be a potent weapon.
With Luton back in the big time, they will now ready themselves to play at the biggest stadiums in the country, but defender Dan Potts said trips to Old Trafford and Emirates Stadium could wait.
"Vegas first," he said, grinning. "We're going to enjoy this moment first and then preparation will start.
