Argentina suffered a significant upset when it lost 2-1 to Saudi Arabia in its first encounter, but rebounded strongly to score two goals against Mexico to take all three points on offer.
“The match against Australia is going to be very difficult. Anyone can beat anyone, it’s all even. We must prepare for the game as we always do. We should be calm and take it match by match," Messi said.
Argentina will now face Australia in the Round of 16 on December 4 after topping the group.
