Gonzalo Higuain scored a hat-trick as Argentina beat South Korea 4-1 at Soccer City to all but book their place in the last 16 of the World Cup.
Higuain struck once in the first half and twice in quick succession after the break as Diego Maradona's side made it two wins out of two in Group B and fired another warning that they are one of the teams to beat in South Africa.
An own goal from Park Chu-Young got Argentina off to the perfect start before Higuain nodded in, and after Martin Dimichelis' error allowed Lee Chung-Yong to pull a goal back, Maradona's side got the goals their dominance perhaps deserved.
Argentina grabbed a 3rd goal after Messi's shot hit the post Higuain tapped in and then warpped up the scoring when Messi's stunning chip enabled Sergio Aguero to cross for Higuain to head home to complete his treble.
It was the first World Cup hat-trick since Portugal's Pauleta in 2002 and the first from an Argentine since Gabriel Batistuta in 1998.
