Stadium, the largest attendance in an MLS Cup final until 2018. MLS limited teams to three substitutions per game in 2003, and adopted International Football Association Board (IFAB) rules in 2005. MLS underwent a transition in the years leading up to the 2006 World Cup. After marketing itself on the talents of American players, the league lost some of its homegrown stars to prominent European leagues. For example, Tim Howard was transferred to Manchester United for $4 million in one of the most lucrative contract deals in league history. Many more American players did make an impact in MLS. In 2005, Jason Kreis became the first player to score 100 career MLS goals. The league's financial stabilization plan included teams moving out of large American football stadiums and into soccer-specific stadiums. From 2003 to 2008, the league oversaw the construction of six additional soccer-specific stadiums, largely funded by owners such as Lamar Hunt and Phil Anschutz, so that by the end of 2008, a majority of teams were now in soccer-specific stadiums. It was also in this era that MLS expanded for the first time since 1998. Real Salt Lake and Chivas USA began play in 2005, with Chivas USA becoming the second club in Los Angeles. By 2006 the San Jose Earthquakes owners, players and a few coaches moved to Texas to become the expansion Houston Dynamo, after failing to build a stadium in San Jose. The Dynamo became an expansion team, leaving their history behind for a new San Jose ownership group that formed in 2007.

Major League Soccer took steps to further raise the level of play by adopting the Designated Player Rule, which helped bring international stars into the league. The 2007 season witnessed the MLS debut of David Beckham. Beckham's signing had been seen as a coup for American soccer, and was made possible by the Designated Player Rule. Players such as Cuauhtémoc Blanco (Chicago Fire) and Juan Pablo Ángel (New York Red Bulls), are some of the first Designated Players who made major contributions to their clubs. The departures of Clint Dempsey and Jozy Altidore, coupled with the return of former U.S. national team stars Claudio Reyna and Brian McBride, highlighted the exchange of top prospects to Europe for experienced veterans to
