We beat the Blues 3-2 at Stamford Bridge on our way to the final and, ultimately, lifting the the trophy back in 1982.
Glenn Hoddle was the inspiration and had a hand in all three goals as we came from a goal down to lead 3-1 and eventually hold out for a 3-2 win.
Mike Fillery opened the scoring, Glenn set-up Steve Archibald's equaliser, scored the second himself and provided the pass for Micky Hazard to put us 3-1 up. Alan Mayes pulled one back but we went on to beat Leicester City in the semi-final before overcoming QPR after a replay at Wembley.
Full-back then, first-team coach now, Chris recalled: "At that stage, with all due respect to Chelsea, as an outfit they weren't as consistently in the top five or six as they are now, but goin there was always a very difficult task.
"I remember the feeling of excitement before the cup ties and going there with confidence, even though it was going to be a battle. It was a great occasion.
"It was an exciting cup tie. If I remember we went behind but we scored three goals in quick succession after the break. Great memories."
Did it seem like 20 years ago? "Looking at the haircuts, yes," joked Chris. "But I remember this one well. Some games are replayed a lot and talked about a lot. This is one of them."
Chris is a firm believer in the magic of the competition and reckons London derbies are as keenly contested now as they were then.
He said: "I heard someone say this week that because there were so many London derbies it takes the edge off, that couldn't be further from the truth.
"Whether it's ourselves, Chelsea, Arsenal, West Ham, Fulham or Charlton they are massive, massive games.
"The added attraction this time is that it's a knockout competition.
"It's a mouthwatering tie but it's all about performing on the day. We managed to do that in the Worthington Cup and we know we'll have to perform well again."
Meanwhile, the Spurs line-up that day at the Bridge was: Clemence, Hughton, Miller, Price, Hazard, Perryman. Ardiles, Archibald, Galvin, Hoddle, Crooks.
Chris Hughton knows all about FA Cup quarter-finals against Chelsea - he was part of a famous win over our London rivals 20 years ago.
