The Semi-Final tie between the clubs that year at Villa Park started with an unremarkable 0-0 draw in the first game, but the teams made up for that with an epic replay at the same venue the following week.

Great goals, tough tackles, a dramatic last-minute missed penalty, a sending off, extra time and one of the greatest FA Cup stikes of all time, it was a match that will take some beating.
And Ryan Giggs, the man who scored THAT goal, will be involved when the teams meet again on Monday albeit from the bench in his role as assistant manager to United boss Louis van Gaal.
"It's a great game to be involved in, a night game, a great atmosphere and I think everyone is looking forward to it," Giggs told FATV.
"I was obviously delighted to score the winning goal in that game and get us to The Final and we'll settle for that this year.
"They'll [the players] see it as if you win this game, you've got a massive chance of getting to The Final, so it's a little mini Cup Final in itself."
Hear from the Manchester United legend about his famous Semi-Final goal against Arsenal from 1999
Giggs also allowed himself to recall that night at Villa Park, when he intercepted a pass from Arsenal’s Patrick Vieira before embarking on a darting run past four men and into the area before firing past David Seaman into the roof of the net.
The goal sent United into The FA Cup Final, where they beat Newcastle United at Wembley, and was the start of an extraordinary few weeks for the Old Trafford club which saw also saw them win the Premier League and Champions League titles.
"It was a special season that year and that game had everything that you could possibly imagine in an FA Cup Semi-Final game," revealed Giggs, who won four FA Cups alongside his 13 league titles, three League Cups and two Champions League honours.
"I never used to like talking about it when I was still playing because I always thought there was more to come, but now I've stopped, I can talk about it as much as I want.
"Unless you've been in that situation, especially when it's a huge goal, you lose yourself and where you don't know what you're doing.
"It's one of my favourite memories of being a footballer. You need so many things to go for you to win The FA Cup that when you do win it, you're thankful for that.
"Until we scored, it was neck and neck really but when we scored there was only going to be one winner.
"To score that goal on that occasion was great for me and it was great for the team in what was a momentous year."
