In 1958, the brilliant Pele was sidelined with a knee injury but was included in the World  Cup squad.

He went on to score in the quarter-final against Wales to become the youngest goalscorer in World Cup history.

An awesome hat-trick in the semi-finals and two goal in the finals set him up for a wonderful career in the game.
