Lionel Messi's Argentina must put aside injured pride after a shock upset by Saudi Arabia and summon the fighting spirit of their similarly-bruised 1990 predecessors if it wants to bring home the World Cup for a third time.

Messi's fifth and final attempt to match Diego Maradona's immortality among Argentinians by winning soccer's greatest prize could not have started worse, with Tuesday's 2-1 defeat to the Saudis one of the tournament's biggest upsets.

Yet he and his disconsolate team might take heart from 32 years ago, when Argentina began the World Cup in Italy with a surprise loss to Cameroon but still went on to reach the final.
