The MLS will invest an extra $37 million in player salaries over the next two seasons.

The league says it will immediately raise the quality of play.

"If you look at our rosters, most teams have between five and six high-quality players," MLS VP of player relations Todd Durbin said on a conference call with reporters on Wednesday. "We needed to find a way to drive more quality deeper into the roster."

The process began last summer, when MLS introduced a program that allowed each team to spend an additional $500,000 on players. These funds, known as "Targeted Allocation Money," notably gave the LA Galaxy the flexibility to sign Mexican national team midfielder Giovani dos Santos.
