At age 20, Lionel Messi scored 16 goals in 40 appearances for Barcelona. Wayne Rooney played 48 games and scored 19 times for Manchester United. At the same age, Clint Dempsey played college soccer. He played 19 games with unlimited substitutions and a countdown clock. Of the 23 members of the United States World Cup squad, 16 were developed in the U.S., and 11 of those played college soccer. I am willing to bet that they were the only 11 players in the entire tournament with college experience.
