Minnows Chorley celebrated pulling off their latest FA Cup sensation in their now-traditional fashion - by belting out a rendition of Adele's 'Someone Like You' in the changing room.
Sixth-tier Chorley, who play in the National League North, defeated a COVID-19-hit Derby side 2-0 on Saturday after Connor Hall and Mike Calveley scored a goal apiece.
The non-league club defied expectations when they beat 2013 champions and League One side Wigan Athletic in the first round and extended their love affair with competition by beating another third tier outfit, Peterborough United, in the second.
After securing a win over second-tier Derby to take another step forward, Chorley's Twitter account posted a video of their players paying tribute to the British singer with their familiar dressing room singalong.
"We just needed a song that was special to us that everybody knew. It happened to be that Adele song," assistant manager Andy Preece said.
"It's just great to share something like that at the end of the game, great for camaraderie.
"You need that togetherness if you're going to win big games. When we got promoted, had big cups wins, it's always been that one."
Chorley, who hail from a northwestern English town near Manchester, have secured their maiden fourth-round berth in the competition and manager Jamie Vermiglio said it was a "monumental day" for a club made up of amateur players.
"I feel privileged to be a part of it," said Vermiglio, who combines his role as manager with his day job as a primary school headteacher in Warrington.
After schools were told to close on Monday due to the coronavirus pandemic, Vermiglio admitted the tie was not top of his priorities.
When it then became clear Derby would need to send youth players to fulfil the fixture - with all the first team and interim manager Wayne Rooney isolating - his thoughts about the game changed further.
"When we were drawn against Derby, the connection of Rooney was the big thing for me. He's an England legend and someone who grew up in Liverpool and has inspired me," said Vermiglio.
"I wanted to compete against him and it wasn't to be - but I'd swap all that for getting through to the fourth round proper.
"Credit to Wayne. I don't know him personally but he phoned me two hours before the game and passed on his well wishes and apologised he couldn't be there."
Vermiglio felt his players had put the town on the map - and possibly secured the non-League club Stg500,000 ($A874,066).
In theory it was a huge upset although, in reality, after a COVID-19 outbreak at the Rams left them without their entire first-team squad, the balance tipped in favour of the experienced part-timers.
Derby fielded a side made up from their youth sides with an average age of 19 and without a single first-team game between them.
"On the financial side, we could possibly get to Stg500,000 ($A874,066) now and for a club like us, not only does it save us, it enables us to grow," said Vermiglio.
