US contends secretary-general Valcke transferred $10million-source

US prosecutors believe FIFA president Sepp Blatter's top lieutenant made $10 million in bank transactions that are central to the bribery investigation of the world soccer body, a source familiar with the matter said on Monday.

Jerome Valcke, FIFA's secretary-general, is described in an indictment filed in federal court in Brooklyn, New York, as an unidentified "high-ranking FIFA official" who in 2008 transferred the sum to another FIFA official, Jack Warner.
