Lionel Messi stole the show in Argentina’s 2-1 World Cup round of 16 win over Australia, but you may have noticed he did it without breaking a sweat.

It’s well known Messi takes his time to get going in a game, which has left him open to criticism.

You’ll never catch him making a lung-busting run to press the goalkeeper or tracking back to stop a counter.

In Qatar, it’s been more prevalent than ever. A graphic shown by BBC Sport before Saturday’s victory calculated which players had walked the longest distance.

Messi’s three Group C appearances against Saudi Arabia, Mexico and Poland were all in the top 10, making him the only player to appear on the list three times.

Exactly why does he do it? Well, a manager who knows him better than anyone summed it up perfectly a few years ago.

“He’s not out of the game. He’s involved,” the Manchester City boss declared. “Moving his head. Right, left, left, right. He smells who is the weak point of the back four. After five, 10 minutes, he has the map. He knows if I move here, here, I will have more space to attack.”

As part of Amazon Prime Video’s ‘This Is Football’ series, Guardiola watched highlights of Messi’s performance against Real Madrid in 2017.

Julian Alvarez doubled Argentina’s lead against the Socceroos after a mistake from goalkeeper Mat Ryan before an Enzo Fernandez own goal with 13 minutes to go made it a nervy finale.

Three minutes later, Lisandro Martinez made a vital block to deny Australia left-back Aziz Behich an equaliser.

Can Messi waltz to his first World Cup triumph in his last as a player? Only time will tell.
