MADRID - Barcelona's Argentina forward Lionel Messi and his father have been accused by Spanish tax authorities of defrauding the state of more than four million euros ($5.3 million). The World Player of the Year and his father Jorge allegedly filed fraudulent tax returns for the years 2006, 2007, 2008 and 2009, according to a spokesman for the prosecutor's office for tax crimes in Catalonia. A Barca spokesman did not immediately respond to a request for comment. Messi, who will be 26 this month, is one of the world's highest-paid athletes with a salary of just over $20 million a season, according to Forbes magazine. On top of his Barca wages, he pulls in around $21 million in endorsements from sponsors and he is 10th on Forbes' latest list of top-earning athletes. –Reuters
