The Galaxy has been trying to create a stronger bond with fans through short documentaries called "Be A Pro," which highlight the various challenges of being a professional soccer player. Klein said the slick videos cost the team "six figures," and they also showcase the products of the Galaxy's main sponsor, Herbalife.
When asked if the battle over Herbalife between investors Carl Icahn and Bill Ackman has had any impact on the Galaxy, Klein shook his head: "We've seen no effect."
A lot has changed for soccer in the U.S. besides the arrival of European stars like Beckham. A generation has grown up playing soccer, and now enjoys watching it.
"There are over 50 million soccer fans in this country," said Klein. "I think now what we're coming to is the realization that there are enough people in this country to keep this a successful sport."
"We're still behind baseball and football, and I believe we always will be, and that's OK," added Kreis.
However, one goal eludes soccer. "I think the next big challenge is getting people to watch our game on TV," said Klein. This weekend's Cup will be broadcast on ESPN, as will next year's World Cup in Brazil, and NBC Sports has been broadcasting many of the MLS games and Premiere League games from England.
"The average attendance in our league, the number of season ticket holders, all the stuff that's happening in the building on a week-to-week basis has been moving in a positive direction," said Kreis, "but the television ratings have not moved very positively."
He thinks it will take five to 10 more years for soccer in the U.S. to reach its full potential. "I'm hopeful that one day we'll be like those old NFL players sitting there and saying, 'Can you remember when it was so bad, and now it's so good?' "
In the meantime, Kreis is looking for victory on the field this weekend, and maybe Real Salt Lake will score financially. "I believe in 2013 the club might actually make some money."
