Jermaine Jones (born 3 November 1981) is a German-American soccer player who plays as a midfielder for Schalke 04 and the United States national team.

Jones has previously played for Eintracht Frankfurt, Bayer Leverkusen and Blackburn Rovers.

Jones was born in Germany and represented them at U21 and senior level. However, he was not a regular in the team. As his father was an American and Jones had not played a competitive match for Germany he was eligible to represent United States. In October 2009, he became a United States player and made his debut the following year.

Jones grew up in Frankfurt-Bonames. His father is an African-American soldier who was stationed in Germany. As a child, Jones lived in Chicago and Greenwood, Mississippi in the U.S. before his parents divorced and he returned to Germany with his mother.

Jones is a good friend of female football player and multiple national champion Steffi Jones, who also is a German-American and the child of an African American soldier. They both started in the same club, SV Bonames (albeit not at the same time). The two are not related.

Thierry Daniel Henry (French pronunciation: [tjɛʁi ɑ̃ʁi]; born 17 August 1977) is a French footballer who plays as a striker for New York Red Bulls in Major League Soccer.

Henry was born in Les Ulis, Essonne (a suburb of Paris) where he played for an array of local sides as a youngster and showed great promise as a goal-scorer. He was spotted by AS Monaco in 1990 and signed instantly, making his professional debut in 1994. Good form led to an international call-up in 1998, after which he signed for the Serie A defending champions Juventus. He had a disappointing season playing on the wing, before joining Arsenal for £11 million in 1999.

It was at Arsenal that Henry made his name as a world-class footballer. Despite initially struggling in the Premier League, he emerged as Arsenal's top goal-scorer for almost every season of his tenure there. Under long-time mentor and coach Arsène Wenger, Henry became a prolific striker and Arsenal's all-time leading scorer with 228 goals in all competitions. The Frenchman won two league titles and three FA Cups with the Gunners; he was nominated for the FIFA World Player of the Year twice, was named the PFA Players' Player of the Year twice, and the FWA Footballer of the Year three times. Henry spent his final two seasons with Arsenal as club captain, leading them to the 2006 UEFA Champions League Final.
