The South Americans, supported by hordes of passionate yellow-clad fans, have been tipped as dark horses for the tournament.

Nestor Lorenzo's men have conceded just one goal so far and boast the attacking prowess of Luis Diaz and 2014 World Cup Golden Boot winner James Rodriguez.

Switzerland have not reached the quarter-finals since 1954, when they hosted the tournament, but impressed in a 2-0 win against Algeria in the last 32.

All four teams will be vying to join the heavyweight line-up for the last eight so far -- France, Morocco, Norway, England, Spain and Belgium.

Spain ended Cristiano Ronaldo's World Cup dream on Monday, beating Portugal 1-0 while Belgium crushed the United States 4-1.
