The veteran midfielder has been an important part of the Galaxy's success over the last few years, and given his history of impressive performances in important matches, there's no reason to believe that Beckham will fail to play at a high level in the championship game.
Along with star teammates Robbie Keane and Landon Donovan, Beckham and the Galaxy will dominate the midfield and win the battle of possession.
With so many talented playmakers in the midfield, the Galaxy forwards will receive plenty of quality passes in the final third that will lead to scoring opportunities.
Even though many of these MLS Cups are not high-scoring games, the Galaxy are fully capable of dominating this match with their attacking play.
Only the San Jose Earthquakes scored more goals than Los Angeles this season, and with Beckham in the starting XI, the Galaxy could easily score two or three goals in the first half.
The Houston Dynamo will not be an easy opponent. The two-time champions are making their fourth MLS Cup appearance and will be highly motivated to defeat the Galaxy after losing to them in the final last season.
Beckham will not be afraid of the moment, even though it will be an emotional night as he ends a very successful career in the MLS.
This is a man who has won six Premier League championships and a Champions League title. He knows what it takes to finish strongly and make the necessary plays to win medals.
He will be focused and full of confidence on Saturday, and you can bet that the excitement surrounding Beckham from the home fans at the Home Depot Center will give his teammates a tremendous boost of energy.
In his farewell match with a championship at stake, Beckham will prove why he's one of the best footballers of our generation with a fantastic performance to lift the MLS Cup for the second time in his career.
