Super Eagles World Cup foes, Argentina, were taught hard footballing lessons by Spain on Tuesday.
Isco scored a hat-trick as the 2010 champions warmed up for next summer’s event by crushing the South Americans 6-1 in Madrid.
Spain raced into a 2-0 lead when Diego Costa stabbed past Sergio Romero before Isco side-footed his first goal.
Argentina, without injured forward Lionel Messi, pulled it back to 2-1 through Nicolas Otamendi’s header.
Isco and Thiago Alcantara extended the lead to 4-1, with substitute Iago Aspas adding the fifth before Isco completed his hat-trick.
The defeat will serve as wake up call to the two-time champions who defeated Italy 2-0 last Friday.
Nigeria and Argentina will avoid each other until the last round of group matches.
