And for Sean Dyche, one of the central figures in the rollercoaster game at Old Trafford in 1997, the tie - and everything that surrounded it - stirs all sorts of different emotions.
It was Dyche, then captain of third tier Chesterfield, who scored the penalty to put the Spireites 2-0 up on the hour mark against 10-man Boro, who'd lost Vladimír Kinder to a red card in the first half.
But it was also Dyche who fouled Juninho and conceded the penalty which gave Craig Hignett chance to draw Bryan Robson's side level after Fabrizio Ravanelli had halved the deficit.
But in between the strikes from Ravanelli and Hignett came the game's big talking point - the ghost goal.
Jon Howard looked to have given Chesterfield a 3-1 lead and almost certainly guaranteed a place in the FA Cup final when his close-range shot smashed the bar and appeared to bounce down over the line, but referee David Elleray didn't award the goal.
For Dyche, is still hurts to this day.

Appearing on Joe Cole and Ashley Cole's Could It Be Magic? podcast , Dyche - now manager of Nottingham Forest - said: “How they missed that is farcical. It’s like the Lampard one at the World Cup. It was that far over. Then it bounces out and [Gianluca] Festa climbs all over Andy Morris, and that would have been 3-1. That changed the whole thing.
“They ended up going in front, with good players like Juninho running all over, by hook or by crook, and then Jamie scored last minute to make it 3-3."
Hewitt's 119th minute goal made it 3-3 after Festa had put Boro ahead in extra-time. The Premier League side comfortably won the replay 3-0 but the first game and everything that surrounded it before, during and after will stay with Dyche forever.
"John Duncan [Chesterfield boss] had the best bit of management still to this day I’ve ever known," says Dyche.
“We are all nervy and he was really quite calm, John, and very dry in the manner he was. We lost him a couple of years ago, rest his soul. Brilliant fella. And very, super helpful to me, both player, coach and manager.
“He was sitting in the dressing room and he said ‘now then lads, I look around and I think you all look like you’re s******g yourself - and I hope you are because I am!’
"Of course I burst out laughing and it diffuses everything. I look back on that, I thought genius. Because I could sense everyone’s nervous. And he went, 'so let’s have a right go’. And he just kept it dead simple.
"I remember after that game thinking genius. We didn’t need tactics, everyone’s too nervous for that.”
Dyche continued: “There were funny side stories at the time.
"Chris Evans invited us on TFI Friday. We had a few beers. He was terrific.
"He said we were watching it and by the end we were screaming at the TV. It was brilliant. Looking back everyone got sucked into it. There was mayhem when Jamie scored last minute.
"It was massive for Chesterfield. It was big for Middlesbrough, of course, but you know, they've got Festa playing, Ravanelli, Juninho...Emerson played in the second game.
“Juninho at that time was arguably one of the best players in Europe. He was great, unbelievable. Little Mark Jules was asked to do a man to man job, I thought we were going to have to stretcher him off.
"Juninho never stopped I swear. He would get it and run all over the pitch, non stop. He could play.”
