Fredua "Freddy" Koranteng Adu (born June 2, 1989) is an American soccer player who plays as an attacking midfielder. He last played for the Swedish Division 1 club Österlen FF.
From before the time of his signing with D.C. United at the age of 14, Adu was spoken of as "the next Pelé". However, he failed to live up to the expectations and, after leaving D.C. United in 2006, he became a journeyman, playing for fifteen teams in nine countries: the United States, Portugal, Monaco, Greece, Turkey, Brazil, Serbia, Finland, and Sweden.
At D.C. United, Adu broke several records. First, he became the youngest athlete ever to sign a professional contract in the United States, after he was selected by the team in the 2004 MLS SuperDraft on January 16, 2004. Three months later, on April 3, 2004, he became the youngest player to appear in a Major League Soccer (MLS) game when he came on as a substitute in a game against the San Jose Earthquakes, and on April 17, he became the youngest scorer in MLS history, scoring a goal in a 3–2 loss to the MetroStars.
Making his full international debut for the United States national soccer team at the age of 16 in 2006, he has won 17 caps for his country and was a part of the US squads at the 2009 FIFA Confederations Cup as well as at the 2009 and 2011 CONCACAF Gold Cups. He also represented the United States Olympic team at the 2008 Summer Olympics.
