( CNN ) -- It 's a 1-0 victory to the U.S . In an age when major nations are doing battle for football 's brightest talents , the American team has pulled off quite a coup . Julian Green is a dual U.S. and German citizen who has been playing for Bayern Munich in Germany since 2010 . The 18-year-old winger 's displays since making his debut for Bayern 's second team in 2013 have been enough to convince U.S. coach Jurgen Klinsmann to offer Green the chance to represent the country of his birth . But the Tampa-born starlet has already represented Germany at youth level , meaning football 's global governing body FIFA had to clear Green to play for Klinsmann 's team . On Monday FIFA did just that , meaning there is nothing stopping Klinsmann from handing Green his international debut against Mexico on April 2 and subsequently taking him to the 2014 World Cup in Brazil . `` We are obviously thrilled , '' Klinsmann told U.S. soccer 's official website . `` We appreciate FIFA 's effort in getting his paperwork approved , and are excited to have him on board for the game against Mexico on April 2 . '' Blog : `` Your country needs YOU ! '' But which country ? Cases like Green 's are becoming increasingly common . In February Spain handed a debut to striker Diego Costa . The Atletico Madrid star has dazzled observers this season , firing his club to the top of the Spanish first division with 23 goals in 27 games . Costa looks likely to spearhead Spain 's defense of its World Cup crown later this year , an ironic twist given the tournament will take place in his homeland . Not only was Costa born in Lagarto , Brazil , he played for the country of his birth on two occasions in March 2013 . But in September of that year the Spanish federation requested Costa be allowed to play for La Roja after he had been granted Spanish citizenship . FIFA obliged Spain 's request , much to the chagrin of Brazil 's football authorities . Manchester United youngster Adnan Januzaj is another player who could spark an international incident . The winger , who impressed upon breaking into the United first team earlier this season , was born in in Brussels , Belgium and is also eligible to play for Albania . The Football Association was thought to be exploring whether Januzaj would be eligible to play for England , while the Football Federation of Kosovo would also call upon the 19-year-old should it ever be permitted to play competitively . Like Green before him , it seems likely that Januzaj will have to pledge his allegiance sooner rather than later .
Julian was cleared to play for Spain against Mexico on June 2 . The young winger previously played for Mexico in youth tournaments . Green was born in Tampa and plays for Bayern Munich 's second team . Former Brazil international Diego Costa recently made his debut for Spain .
