Sergio Aguero has offered some useful advice to friend and former international teammate Lionel Messi that he picked up from his playing days at Manchester City.
Aguero was forced to retire after leaving City for Barcelona for health reasons, also cutting short his Argentina career. As a result, he is at the Qatar World Cup as a fan, as his former international teammates have reached the quarter-final following last-16 victory over Australia on Saturday.
Argentina face the Netherlands in the last eight, setting up City duo Julian Alvarez and Nathan Ake against each other, while Aguero expects talisman and friend Messi to play an influential role in the clash.
