I want to know the answer to the following question:
Where did Messi, Iniesta and Xavi learn their football in Barcelona?
All the background I'm provided with is that "In 2010, the club made history when three players who came through its youth academy (Messi, Iniesta and Xavi) were chosen as the three best players in the world in the FIFA Ballon d'Or awards, an unprecedented feat for players from the same football school.". Is that enough to answer the question?
