Lionel Messi has warned his Argentina team-mates they have a "very tough" game ahead as they prepare for their World Cup clash with Australia.
The Albiceleste lost their opener against Saudi Arabia, but responded with back-to-back victories to set up a meeting with the Socceroos. After beating Mexico 2-0, they won by the same scoreline against Poland to leapfrog the European side.
Messi didn't have the best of games on Wednesday, winning a controversial penalty but seeing his spot-kick saved by Wojciech Szczesny. He recognised it hasn't been plain sailing for Lionel Scaloni's side, and laid bare the situation during an interview after the game at Stadium 974.
