The strike also marked his 14th World Cup goal overall and came on the occasion of his 200th appearance for Argentina and his sixth World Cup tournament.

At nearly 39 years old, Messi became the oldest player to score both a World Cup hat-trick and a brace in the competition’s history.

Argentina dominated proceedings despite Algeria enjoying periods of possession, with Messi’s clinical finishing proving decisive.

A fourth Argentine goal and another by Algeria were disallowed for offside.

The win gives Argentina an ideal start in Group J.
