Fresh off his Champions League final victory, Messi arrived in Buenos Aires on Tuesday. His Argentine team and Brazil are favored in the continental championship that begins July 1 with Argentina facing Bolivia. The final is July 24.
"I've had the luck to win everything with Barcelona, win everything as an individual, and my goal now is go win things for the Argentine national team," Messi said at the airport in Buenos Aires.
Messi was the man of the match in Barcelona's 3-1 victory over Manchester United on Saturday. He has, however, had limited success with his national team.
Maradona has since been replaced by Sergio Batista as coach. Argentina has won the World Cup twice — 1978 and 1986 — but it has not won a major international tournament since taking the Copa America in 1993 in Ecuador.
