Now that America has both players, here's the question: What style of player will make a bigger impact for MLS; Adu or Beckham? Breakdown: Freddy Adu: The biggest prodigy signing in MLS history. MLS signs him and bills him as the next-big-thing, and EPL/the world kept an eye on him with DC United with the thought that he could one day play in EPL, possibly Man U. David Beckham: The biggest international signing in MLS history, and the history of American sports. He may still be at his prime, but he will be 36/37 when he finishes his contract with LA Galaxy.
