Gabriel Martinelli the latest World Cup super sub to make big impression at the World Cup

The World Cup isn't just about the eleven players starting a game; it's a real squad effort, and that's why it's imperative to get the right 26-man squad for the tournament. 

Every side may have its ideal starting XI, but the potential for substitutes to change a game can not be undervalued, and there have been plenty of footballers who have made the most of their World Cup minutes by coming off the bench. 

Gabriel Martinelli became the latest player to etch his name into that category when he produced a 95th-minute winner for the South Americans after coming on as a substitute in their Round of 32 meeting with Japan. 

Time and time again over the years, the 'finishers' have proved why they have earned a place in their nation's squad by coming up with the goods that change their team's fortunes and the course of the competition. 

At Italia 90, Totò Schillaci became an overnight sensation by coming off the Italy bench and going on to win the World Cup Golden Boot, while Roger Milla's introduction at the same tournament is the stuff of legend. 

Then there's the ultimate World Cup sub in Mario Gotze. The German forward entered the fray in the 2014 final and became a national hero by netting the goal that won his country the World Cup in Brazil.

It's a lesson in relying on your whole squad, rather than just the starting XI.
