The 83,000 screaming fans were not disappointed in Lionel Messi and his Argentina team's first international match since lifting the World Cup title last December. Messi's Argentina beat Panama 2-0 with two late goals Thursday night at the Monumental de Nunez Stadium in Buenos Aires, in the first of two matches for the team to celebrate its triumph in Qatar. Thiago Almada opened the scoring in the 78th minute, pushing the ball into an empty net after a free kick taken by Messi hit the post.
