Chris Richards (Bayern Munich)
Twenty-year-old Chris Richards has been tipped as the long term successor to Jerome Boateng at Bavaria. The American starlet was a key figure in Bayern's reserve sides and recently made his first start for the German giants against Hertha Berlin, providing an assist for Robert Lewandowski in the 51st minute.
Alex Mendez (Ajax)
American youth international midfielder Alex Mendez has been promoted to Dutch powerhouse Ajax's Champions League roster following his consistent displays for Jong Ajax. The LA Galaxy youth product has had a slow start to life at Amsterdam but is expected to thrive in Ajax's attacking system and earn a first team place in the near future.
Konrad de la Fuente (Barcelona)
La Masia starlet Konrad de la Fuente has already caught the attention of Barcelona manager Ronald Koeman with his impressive displays down the flanks in the youth team. The speedy winger became the first American to play for the Catalans' senior team when Koeman brought him on in the second half in a pre-season friendly against Gimnastic Tarragona.
Sergiño Dest (Barcelona)
On October 20, Sergino Dest became the first US player to appear for Barcelona in a UEFA Champions League match.
The highly-rated right-back has dazzled since his £23 million move from Ajax and has cemented a starting position with his stellar display in the recent El Clasico, amid being on the losing side. The American international will have a big part to play in Barca's progression to the latter stages of the Champions League.
