World Cup 2022: Poland beat Saudi Arabia, France meet Denmark, Argentina's backs to the wall

There are three European sides in action on Saturday: Poland, France and Denmark. But the most significant game of the day looks set to be Argentina v Mexico with the losing side crashing out of the competition, so both Latin American football powerhouses will be fighting for victory in Qatar on Saturday night. 

Australia run out 1-0 winners, thanks to a Mitchell Duke header from a cross by Craig Goodwin in the first half.

Tunisia and Australia met for just the third time in history, with the last match a 2-0 Tunisia victory in the 2005 Confederations Cup.

Poland's 2-0 victory puts them top of Group C with four points, while Saudi Arabia are in second place on three points despite their defeat -- with Argentina and Mexico to play later. 

Piotr Zielinski gave Poland a late first-half lead, before goalkeeper Wojciech Szczesny made an amazing double save when Saudi Arabia were awarded a penalty. 

First he plunged to his right to keep out Salem Al Dawsari's penalty, before leaping to his left to deflect Mohammed Al Burayk's follow-up over the bar. Already people are talking about the save of the tournament.
