The World Cup is widely viewed as the greatest sporting event on earth, but scoring in the tournament has been a wildly up-and-down matter.
USA '94 saw an improvement as the average rose considerably to 2.71, no doubt influenced by the sweltering climates players had to contend with, resulting in more open affairs. But defences grew meaner again from 1998-2010.
Supporters were treated to an average of 2.64 goals per game, a more than respectable figure bettered by the fact that an impressive 10.07% of shots were converted as the drama unfolded in Brazil.
The efficiency of the world's sharp-shooters helped to provide a vast improvement on 2010, when only 7.93% of shots found the back of the net.
FIFA World Cup goalscoring has evolved; will the evolution continue in 2018?
