Although David Beckham is leaving the Los Angeles Galaxy after Saturday's Major League Soccer Cup, he plans to play a major role in the league's growth indefinitely.

Beckham began his last few competitive days in a Galaxy uniform Thursday with a training session for the defending champions' final match against the Houston Dynamo.

The former England captain says he nearly ended his Galaxy career last year after raising the trophy, but decided he still had unfinished business.

Beckham won't say where he plans to play next, but he reiterated his commitment to MLS, both as a future team owner and a supporter of North American soccer.

One part of MLS still bothers him: Even after six years, Beckham says he's still getting used to calling his sport soccer, not football.
