1994 FA Cup winner Paul Parker fancies Cardiff City to cause an upset at Wembley on Saturday.

"I think this will be a great FA Cup final for neutrals, even though it is not between two of the so-called 'Big Four'.

Portsmouth and Cardiff City have got there on merit and you know for sure that this game will mean everything to them.

Both sides will try to deliver a spectacle - unlike the sterile affair we had last season between Manchester United and Chelsea. What a powder-puff final that was.

If those two teams were playing again this year, just four days before the Champions League final, it would be a sideshow - the one trophy neither side really wanted to win.

No danger of that this time. For Cardiff in particular it is literally a once-in-a-lifetime experience. It will be the biggest day of their playing careers and they will be desperate to give a good account of themselves.

The big teams must realise they have to match the minnows' passion if they want to win the FA Cup, which is still undeniably a great tournament.

I played in the 1994 final for Manchester United and, although we won the Double that year, it was a wonderful occasion.

Winning the league is a bit different - it is recognition of your consistency over the course of a season. But in terms of a single occasion, nothing matches the Cup final.

It is one of those things you always dream about, and when you realise that dream it is really unforgettable.

You have all the build-up, walking out at Wembley in your suits, and of course the night out afterwards.

Additionally we had the United song with Status Quo, which got to number one although I must admit I didn't play a leading part!

Portsmouth are out of form after finishing the season badly. Admittedly Harry Redknapp rested a lot of players, but personally I think it is better to make sure you go into a game with some momentum.

With Jermain Defoe cup-tied, I just hope Harry doesn't go for the 4-5-1 formation he used against West Brom in the semi-final.

Pompey were unconvincing that day, and they should go for it against Cardiff. It's all very well saying Milan Baros and David Nugent are out of form, but both men have enough quality to do the business against Cardiff.

I can't really understand the controversy about Cardiff representing England in the UEFA Cup. If they get there they will have earned it.

If you don't want them representing England then don't let them in the league in the first place. I say good luck to them.

I hope they have a real go and get stuck into Portsmouth. Obviously it's tough to make a prediction, but I just fancy an upset and am backing the underdogs to nick it one-nil."
