Sharjah24 - AFP: On Saturday, Argentina will face a fight to remain in the World Cup as Lionel Messi and his colleagues gear up to take on Mexico in a game they cannot afford to lose.
In the early kick-off in Qatar, Australia beat Tunisia 1-0, recovering from a chastening opening defeat against defending champions France to keep their hopes alive.
Two-time world champions Argentina, who arrived in Qatar on a 36-match unbeaten run, are in a precarious position after a stunning 2-1 defeat to Saudi Arabia.
The Argentines said they would draw on memories of superstar Diego Maradona, their 1986 World Cup-winning captain who died two years ago this week, to inspire them against the Mexicans.
"We keep him in mind. He was a very important person in world football, and not just for us Argentines," said Inter Milan forward Lautaro Martinez.
"Today is a sad day for everyone and hopefully tomorrow we can give happiness."
The surprising Saudis have a chance to prove they are no flash in the pan when they face Poland and Robert Lewandowski, the prolific striker who is still looking for the first World Cup goal of his career.
The Barcelona forward missed a penalty in the goalless draw against Mexico in Group C.
Australia, who were beaten 4-1 by France, won a World Cup game for only the third time in their history at the Al Janoub Stadium.
Striker Mitch Duke scored the only goal of a tight game with a clever header in the first half and Australia desperately held on to silence Tunisia's vociferous fans.
The Socceroos sit second in Group D with three points from two games, with a game to come against Denmark.
"As a striker you need to have that confidence and believe that you can score in every match," said Japan-based centre-forward Duke, 31.
"I actually was messaging some of my family saying that I was going to score today."
