The boss has been touched by that magic as much as anyone.
In a glittering playing career at the Lane he played in five finals (counting replays) including one of the greats in 1981, scored in two and netted the winner against QPR in 1982.
Indeed, it was somewhat fitting that he bowed out from Spurs in 1987 in another memorable final - this time on the wrong end of 3-2 defeat against Coventry City.
"It's all about tradition. I don't think anything has been taken away from the competition and it's coming back round again after the couple of years where people were tinkering with it.
"The FA Cup has always been the second thing domestically behind the league championship.

"We've got a good history and we want to go all the way if we can. That's what we're striving to do by going down to Southampton and knocking them out hopefully."

"No need to reminisce!" he joked. "We've got players who have experienced cup finals, Gus, Teddy and they know what it's about."
Glenn Hoddle believes the magic of the FA Cup is back - if it ever went away.
