The Galaxy-Barca game has already sold 75,000 and should surpass the two biggest crowds of the summer -- 82,252 for Mexico-Haiti at the new Dallas Cowboys Stadium and 81,224 for Chelsea-Inter Milan last week at the Rose Bowl.
Argentine star Lionel Messi heads the list of players in the team that arrived Wednesday in Los Angeles. He led Barca to a rare triple in 2009.
In addition to the stars from last season's triple championship team, recently acquired Zlatan Ibrahimovic and Mexican teenager Jonathan Dos Santos -- brother of Tri Gold Cup hero Giovanni -- are in the traveling squad.
Ibrahimovic will be in Pasadena for his second game in two weeks. He was with Inter Milan for its game against Chelsea in the World Football Challenge.
The Catalan club's star-studded team, playing in the United States for the third time in the last four years, continues to Seattle to play Seattle Sounders FC on Wednesday -- the game at Qwest Field is already a sellout -- and concludes its tour on Aug. 8 at San Francisco's Candlestick Park against Mexico's Guadalajara.
