Carlos Tevez laid on two goals and scored a third as Argentina beat world champions Spain 4-1 in a friendly at the Monumental on Tuesday.
Argentina, rebuilding after World Cup coach Diego Maradona was let go, scored two early goals in the space of three minutes.
Lionel Messi, appearing marginally offside, chipped brilliantly over Pepe Reina from a through ball by Carlos Tevez, who minutes earlier shot just wide in Argentina's first attack.
Gonzalo Higuain scored the second from a narrow angle after being put through by Tevez, again justifying coach Sergio Batista's decision to field him in a three-man strike force, and rounding Reina.
The goalkeeper was at fault with the third just past the half hour. He slipped going to kick a back pass by Alvaro Arbeloa and the busy Tevez was rewarded for a trademark chase by just beating Reina to the ball to scoop it in close to the near post.
Fernando Llorente pulled one back from fellow substitute Pedro's square ball into the middle of the box with six minutes remaining before Serio Aguero headed a stoppage-time fourth for Argentina.
"Argentina played very well, we have to recognise that," Spain coach Vicente del Bosque told a news conference.
"It's beneficial to the squad to know how to play the weak teams like Liechtenstein and also the big ones."
"I think Argentina had a lot of merit in preventing (the crowd) from seeing the Spain we saw in the World Cup," his oppositite number Batista said.
Spain, who started with three second string players in the back four, were not allowed to settle comfortably into the close passing game that helped them win the World Cup in South Africa in July.
They came more into their own towards the end of the first half.
When the score was still 2-0, a David Villa free kick hit the angle of post and bar and Argentina had another narrow escape five minutes before the interval.
Again Villa, looking to equal Raul's Spanish record of 44 goals, took a free kick aimed to Sergio Romero's left. The shot took a slight deflection on Javier Mascherano at the edge of the wall and beat the diving Romero but hit the post. Gabriel Heinze then blocked Silva's effort from the rebound.
Spain, having made a number of halftime substitutions, almost pulled one back early in the second half when Fernando Llorente headed wide from Jesus Navas's right cross.
Argentina, crushed 4-0 by Germany in the World Cup quarter-finals, benefited from the return of Esteban Cambiasso in midfield although the success story in that department was Ever Banegas.
Banegas, who like Cambiasso missed the World Cup, was everywhere in midfield supplying the forwards after helping Mascherano with the ball winning for a team that did not need to depend excessively on Messi.
Messi showed where his importance to Argentina lies just past the hour, having been quiet since the resumption. He weaved his way through the defence from the right to pass to the left where substitute Angel Di Maria scored, but the goal was ruled out for offside.
"He's finally won over the crowd, that's good for the image he gives of us in the world," said defender Martin Demichelis referring to criticism at home that Messi does not play as well for Argentina as Barcelona.
From another Spain free kick Santi Cazorla had a shot tipped onto the bar by Romero, one of several chances that went begging for Spain who dominated possession in the second half.
