Sheffield United manager Nigel Clough saluted his players as they claimed a second Premier League scalp in the FA Cup with a 1-0 victory over Fulham.
Substitute Shaun Miller scored the only goal of a low-key fourth round replay at Craven Cottage in the final minute of extra time to set up a last-16 meeting with either Nottingham Forest or Preston at Bramall Lane.
Having seen off another top-flight side on their own patch in the shape of Aston Villa in the third round, Clough's League 1 strugglers once again upset the odds.
He said: "It was a remarkable effort again by the players, and we had two or three thousand supporters out there loving it.
"If you hang on in there at 0-0 you've always got an opportunity.
"I thought we did enough during the game to get one, but we didn't think it was going to come that late.
"You sense this about the group, we had a bad off day on Saturday at Crewe (where they lost 3-0), we've put it behind us and produced another performance tonight.
"To score 30 seconds before the end, it's special again, but we have to improve in the league."
Clough could now come up against his former club Forest in the fifth round, with the City Ground outfit facing their own replay away to Preston on Wednesday night.
On the prospect of an emotional reunion with Forest, he added: "We'll see, we don't mind anybody, we look forward to another good cup game at Bramall Lane."
