FC Barcelona's supporters unveil a giant banner reading in Catalan 'La Masia, don't touch it' prior to the Spanish La Liga soccer match between FC Barcelona and Betis at the Camp Nou stadium in Barcelona, Spain, Saturday, April 5, 2014. Barcelona has been "the victim of a grave injustice" after being hit with a FIFA transfer ban, Josep Maria Bartomeu said on Thursday as the Spanish champion vowed not to change its model for recruiting youth players. Bartomeu told a news conference the club has never broken any Spanish regulations in signing young talents to its famed La Masia academy, which has produced such players as Lionel Messi, Xavi Hernandez, and Andres Iniesta.
