A lot has changed in football since Portsmouth lifted the FA Cup for the first and only time in 1939.
But one tradition that has survived the massive transition in the game over the years is the belief you need a bit of luck to end up winning the famous old trophy.
Science usually wins over superstition but fans, players, managers and chairmen alike are happy to believe otherwise when it comes to preparing for a big match.
And they were proved right when Pompey won the last final before the Second World War.
Their opponents, Wolves, were managed by the flamboyant and forward-thinking Major Frank Buckley, who thought a special diet featuring monkey gland supplements would see his side home.
Pompey boss Jack Tinn, meanwhile, put his faith in his lucky spats - fabric shoe covers that were popular at the time and which he wore for every Cup tie, keeping them in a safe between games.
Wolves were hot favourites but the shoes beat the monkeys hands down.
Now, 69 years later, Portsmouth's chief executive Peter Storrie thinks the club playing in an all-blue strip, rather than their usual blue-white-red shirt-shorts-socks combo will bring success against Cardiff at Wembley on Saturday
Storrie gave the go-ahead for the colour change because it was a one-off kit used for the semi-final against West Brom, which of course Pompey won.
The Premier League club have also gone for the same east dressing room and chosen the same end for their fans that they had against the Baggies.
Portsmouth boss Harry Redknapp is no stranger to superstition himself.
He wore the same shirt, tie, pants and jacket during a 20-match unbeaten run while in charge at Bournemouth, and repeated the trick during his first spell as manager of Pompey.
Redknapp has also forbidden any of his squad, or his assistant Tony Adams, from touching the FA Cup during promotional appearances in the run-up to the final.
So, of all people, Redknapp will identify with Portsmouth's 1939 winger Freddie Worrall, who never travelled without his mascots and took all five of them on the field at Wembley.
He carried a small horseshoe in his pocket, pushed a sprig of white heather down each sock, tied a small white elephant to one of his garters and put a lucky sixpence in his boot.
Worrall, possibly the most superstitious player who ever lived, was also the man that Tinn entrusted to put on his spats before every game.
All that effort paid off on the day though, with Pompey roaring into an early lead against Wolves.
Bert Barlow opened the scoring when he latched on to a Jock Anderson pass and fired home with a rising shot.
And just before half-time Worrall, surprisingly able to run despite the number of lucky charms he was carrying, set up Anderson to make it 2-0.
Cliff Parker added a third goal a minute after the break, following up to slide home after Barlow's shot was saved by Alec Scott, and then taunted the keeper by shouting: "That's my first Scotty. I'm coming back for another."
Dicky Dorsett replied from eight yards for Wolves but Parker kept his promise by heading home his second goal from Worrall's cross to complete a 4-1 victory.
Not so lucky was the amount of money Pompey made from their triumph - they got £20 a player - less than the band who played before the game.
"We would have been better off playing the cornet," said skipper Jimmy Guthrie.
The lack of money was not the only worry for the players - within months, World War II would begin and, with the football programme suspended, all of Pompey's players had their contracts terminated.
They all survived the conflict but sadly none have lived long enough to see the club return to Wembley.
BBC Sport profiles the Pompey heroes that Redknapp's side will try to emulate on Saturday.
MANAGER - Jack Tinn In charge when Pompey lost the 1929 and 1934 finals, he put this success down to his lucky spats and had always said his side would win it in 1939.
