Coventry stunned Premier League Wolves with two goals in injury time to seal an amazing 3-2 win and book a first FA Cup semi-final appearance since 1987.
The Sky Blues went on to win the competition that year in one of the most famous finals ever and they kept their hopes of another unlikely triumph this season alive after a remarkable climax at Molineux.
It looked like they would be leaving with broken Hearts after two goals in the final 10 minutes from Rayan Ait-Nouri and Hugo Bueno overturned Ellis Simms’ opener and seemed to set a Wembley date for Wolves.
But the Championship side were not done and in nine minutes of time added on they turned the quarter-final tie around again, with Simms grabbing a second and then Haji Wright earning himself folklore by grabbing the winner.
It was a dramatic ending to a breathless Derby, which the Championship side probably deserved to win.
Coventry survived a couple of early scares as Mario Lemina and Nelson Semedo missed chances, but having absorbed the pressure, the visitors missed a golden chance of their own to go ahead and Simms will not want reminding of it.
After Jose Sa had palmed Kasey Palmer’s shot into the path of Jake Bidwell, the wing-back set up a simple tap-in from close range after rolling the ball across goal, but Simms got his feet in a mess and somehow put his shot straight at Sa.
The momentum had suddenly switched and two more glorious chance came for Coventry before half-time as Simms played in Milan van Ewijk, who looked prime to score until Sa made a fine block and the Wolves keeper was grateful to an unmarked Palmer for cushioning the ball straight at him.
The Sky Blues finally made the breakthrough eight minutes after the restart as Simms made amends for his earlier howler.
Liam Kitching headed a free-kick back across goal to the far post where Simms appeared to bundle the ball in with his arm.
But it survived a lengthy four-minute VAR check to give the travelling supporters a second chance to celebrate.
They should have been celebrating another goal soon after as their side bombarded Wolves’ goal.
Sa had to make a double save, first keeping out Wright’s effort with his feet and then parrying away Josh Eccles’ effort from the rebound.
After Sa then rolled the ball to Matt Doherty, the Republic of Ireland wing-back was dispossessed in a dangerous area and Palmer put a shot agonisingly wide.
They could have done with one of those chances going in as the inevitable Wolves onslaught came in the final 20 minutes.
Joao Gomes saw a vicious effort tipped onto the post by Bradley Collins and then Ait-Nouri hit the other post with a header soon after.
But Wolves remained ragged at the other end and only a one-man show from Sa stopped Coventry from killing the tie.
The Portugal keeper pulled off three big saves to keep the score at 1-0, palming away efforts from Simms and Callum O’Hare and then denying Kitching at close range.
And he was rewarded as Wolves levelled in the 83rd minute when Joel Latibeaudiere could not clear a cross and Ait-Nouri slammed home the loose ball.
The writing appeared on the wall for Coventry as Ait-Nouri surged forward, playing in Bueno, who made no mistake.
But in the sixth minute of time added on Simms headed home at the far post after Bobby Thomas had flicked on Bidwell’s cross.
There was time for more drama as in the 10th minute Simms teed up Wright to steer Coventry to a famous victory.
