Lionel Messi watches Isco score hat-trick as Spain hit Argentina for six

Isco scored a hat-trick as Spain romped to a 6-1 victory over Argentina in Madrid, where Lionel Messi again watched from the stands.

Barcelona playmaker Messi had been expected to return after missing Friday's 2-0 win over Italy in Manchester as a precaution because of an abductor muscle injury.
