FIFA has finally acknowledged that there may be something wrong with the Jabulani World Cup ball, but won't act on the problem until after the tournament, AP reported. Many players have likened the Jabulani to a «supermarket ball,» saying it is too unpredictable and flies through the air too easily. «We're not deaf,» FIFA secretary general Jerome Valcke said Saturday at a news conference. «FIFA is not unreceptive about what has been said about the ball.» Valcke said that FIFA will discuss the matter with coaches and teams after the World Cup, then meet with manufacturer Adidas. -- SPA
