Blatter has hit the headlines with a number of proposals in recent years, including making the World Cup a biennial event, increasing the size of the goals, and introducing skimpy shorts in the women's game.

"A mere shaking of the head or mild criticism are no longer enough. Stronger words are needed. This President is clearly off his head," he told German daily Bild.

Without his famous afro hairstyle, but no less opinionated, Breitner also branded 70-year-old Blatter "power hungry and extremely vain", adding that he "does not think or act like a professional footballer, because he never was one."
