(CNN) -- Argentina's star-studded team went top of South America's 2014 World Cup qualifying group as Lionel Messi inspired a 4-0 thrashing of Ecuador on Saturday.

With his top Europe-based players to call on, coach Alejandro Sabella saw his side effectively end the match with three goals after only half an hour.

Sergio Aguero, top scorer for English champions Manchester City last season, broke the deadlock in the 20th minute as he celebrated his 24th birthday in style.

Strike partner Gonzalo Higuain, who helped Real Madrid to the Spanish title, doubled the lead nine minutes later.

Barcelona's three-time world player of the year Messi made it 3-0 two minutes later to continue his unbelievable scoring form, having netted 73 times for the Spanish club in the recently-completed 2011-12 campaign.

Real Madrid winger Angel Di Maria wrapped up the scoring with 15 minutes to play as Argentina moved up to 10 points from five games, just ahead of Chile.

Messi was key to the victory, which came ahead of next Saturday's friendly against Brazil in the United States. The 2014 hosts lost 2-0 to Mexico in a friendly in Texas on Sunday.

He combined with Di Maria to set up Aguero's opener and then linking with Higuain for his own goal before also setting up the final effort.

Chile moved onto nine points from five matches with a 2-0 win over bottom team Bolivia, who had Luis Gutierrez sent off in the second half.

Midfielder Charles Aranguiz scored against the run of play just before halftime in La Paz, then Gutierrez saw red for a foul on Barcelona's Alexis Sanchez before Juventus midfielder Arturo Vidal wrapped it up with seven minutes to play.
