As the American commentators said before the start of the game, the stadium is full because many people, including Americans, came to see the legend play - referring to one of the today's greatest players - Lionel Messi.
Argentina is playing USA in Houston, TX on June 21st, 2016. Not an easy game, because the American team is pretty strong. Coming from not being a popular sport to a strong place among the football teams around the world, for USA this is a very important game, because the Argentina national football team is one of the strongest in the world.
And already 50 minutes into it, Argentina scores three goals thanks to Lionel Messi, Ezequiel Lavezzi and Gonzalo Higuain - the players to watch! Including Sergio Aguero and Javier Mascherano.
