In 1958, France's Just Fontaine scored 13 goals to win the Golden Boot – the prize given to the tournament's top goalscorer. But despite Fontaine's award, his team-mates went home empty-handed after France lost to eventual champions Brazil. Since then, defences have grown tighter and more sophisticated, and Golden Boot winners now score fewer goals. Last time out, Thomas Müller of Germany won the award with just five. The tournament as a whole has also seen a decline in goals. In 1954, the average number of goals per match was 5.38. For the the most recent World Cup, it was almost half that, at 2.27. To what extent do top goalscorers ensure a team's World Cup victory?
