Fifa bribery allegations concern sponsors
Two of Fifa's largest sponsors - Coca-Cola and Adidas - have expressed concern at the widely publicised in-fighting at Fifa.
But on Monday, Fifa President Sepp Blatter denied there was a crisis. At a news conference in Zurich, he acknowledged Fifa was in difficulties, but insisted that the organisation could solve its problems by itself.
