25 November 1964

In November 1964, Bill Shankly had a brainwave: to send his team out in all red.

In doing away with white socks and trim, Shanks thought his team would be more intimidating. He was right.

Writing about the change in his autobiography, striking legend Ian St John recalled: "Shankly thought the colour scheme would carry psychological impact - red for danger, red for power.

"He came into the dressing room one day and threw a pair of red shorts to Ronnie Yeats. 'Get into those shorts and let's see how you look,' he said. 'Christ, Ronnie, you look awesome, terrifying. You look 7ft tall.'"

St John went on to claim the red socks were his idea.

Whoever claimed the credit, the overhaul proved inspirational. The kit's first outing brought a massive scalp as Anderlecht were beaten 3-0 in the European Cup, with Roger Hunt joining St John and Yeats on the scoresheet.

Six months later, Liverpool stepped out onto the Wembley turf dressed all in red and won the FA Cup for the first time.

No-one knows if Leeds really were intimidated by their opponents' attire on the day, but the trophies brought to Anfield over the next 25 years provided ample proof that Shanks' brainwave was one of the most important decisions in the club's history.
