Adu signed a professional contract at the age of 14 and was selected by D.C. United as the number one overall pick in the 2004 MLS SuperDraft. After making his professional debut against the San Jose Earthquakes on April 3 as the youngest player on a major U.S. pro team in more than 115 years, Adu was a member of Peter Nowak's 2004 MLS Cup championship squad. The US international finished his first season with five goals and three assists after notching his first professional goal on April 17 in a 3-2 loss to the MetroStars, thus becoming the youngest goal scorer in MLS history. Named an MLS All-Star in 2004 and 2006, Adu scored 11 goals and added 17 assists in 87 appearances with the Black-and-Red.

After three seasons with United, Adu was transferred on December 11, 2006 to Real Salt Lake, where he scored two goals in 11 total appearances. Halfway through his first season in Salt Lake, weeks after he scored three goals against Poland at the 2007 Under-20 World Cup, Adu’s rights were secured by Benfica. Adu made his debut with the Portuguese First Division club on August 14, 2007 against Copenhagen in a UEFA Champions League qualifying match, coming in as a 37th minute substitute. Adu went on to score two goals in 11 games with Benfica's first team.
