When Don Revie took charge of Leeds United in March 1961 they were struggling in the old Second Division and had never won a major trophy, but he soon transformed them into one of the best sides in the country.
They won the league and secured promotion in 1964, before winning the League Cup in 1968 and being crowned champions of the First Division the following year.
The club enjoyed a lot of success during Revie's tenure, who remains their most successful manager of all time, but they also suffered plenty of heartache.
In 1965, they lost the FA Cup to Liverpool in extra-time and narrowly missed out on their first league title. Despite finishing on the same points total as rivals Manchester United (61), they lost out on goal difference.
They then lost the FA Cup final to Chelsea (after a replay) in 1970 and in 1971 finished just one point behind Arsenal in the league.
Revie was a hugely talented manager and his physical, win-at-all-costs approach proved to be very effective, but he was also deeply superstitious and believed that Leeds often fell victim to bad luck.
To ensure his side would get the rub of the green, he wore a lucky blue suit to all important matches, even when it began to fall apart, and he is said to have carried a rabbits foot into the dugout.
On home matchdays he would also walk to a particular set of traffic lights and retrace his steps, refuse to go back to his house after leaving and make the players run out onto the pitch in a certain order.
He had several strange phobias too, including a deep-rooted fear of feathered birds and he urged the club to scrap its owl badge and shake off the nickname 'The Peacocks' - as he believed they were bad luck.
After falling agonisingly short of silverware on several occasions Revie had also convinced himself that Elland Road was cursed.
He believed that a group of gypsies were angry about being forced to move off the scrubland where the stadium was built in the 1890s, and they had placed a hex on it before they left.
So in 1971, after a run of bad results, the manager invited a fortune teller called Gypsy Rose Lee, who lived in Blackpool, to travel to Elland Road.
According to various accounts, she walked onto the pitch, scratched the grass and threw some seeds down. She then walked to all four corners of the pitch and did the same, before telling Revie, over a cup of tea, that the curse had been lifted.
