Sir Alex Ferguson's Red Devils start as 1-10 favourites in their first final since sitting out the 2000 competition to play in the World Club Cup.

And Millwall, who are sweating on the fitness of player-manager Dennis Wise, have been written off by many pundits.

But they will be hoping to spring a Cup shock in front of 72,500 fans on one of British sport's biggest occasions.

On paper, the Lions have little chance against the Old Trafford all-stars, including Ryan Giggs, Paul Scholes and fit-again talismen Roy Keane and Ruud van Nistelrooy.

But second-tier sides have pulled off huge upsets in the past, as when Southampton toppled United in the 1976 final.

And Millwall chairman Theo Paphitis believes a fairytale ending is on the cards.

Feature: Lions ready for dream

"It is a great, great opportunity for us as an FA Cup Final is something that dreams are made of," he said.

His team's task will not be easy however.

Following Manchester United's much-criticised absence in 2000, Ferguson has warmed to the competition and this year's finale is his last chance to end a barren season.

Feature: Cup of salvation?

"We've not been in a final for five years and I think we've served our penance for not going," Ferguson said after the 1-0 semi-final win over Arsenal.

Whatever the result, the Cup Final has traditionally been a big day out for fans and police have stepped up security in a bid to ensure that nothing spoils the occasion.

Armed officers will carry out random checks on lorries coming into Cardiff before the game.
