Intro:

Sergio Agüero trained on Wednesday after missing the last 16 victory over Switzerland because of a muscle injury in his left leg. Argentina take on Belgium in the World Cup quarter-finals at the Estádio Nacional, Brasília, on Saturday (KO 17:00 BST).

Script:

Lionel Messi doesn't seem too bothered but Argentina have been criticised for being too reliant on the four-time World Player of the Year.

Sergio Agüero will hope to reduce the goal-scoring burden as he trained following a muscle injury in his left leg.

The two-time champions take on Belgium in the World Cup quarter-finals at the Estádio Nacional in the capital Brasília on Saturday.

The Europeans are far from in top form themselves, after needing extra-time to defeat the USA in the last round.

Argentina and Belgium have played each other four times before, with the South Americans emerging victorious on three occasions.

Messi has scored four times at this World Cup and set-up Ángel di María for the winner against Switzerland in the last 16 on Tuesday.

In the last eight, La Nuestra will hope to rediscover their style.
