Fifa president Sepp Blatter is appealing against his 90-day ban from football's world governing body, reports BBC Sport.

The 79-year-old Swiss has been suspended from all duties while Fifa's ethics committee investigates corruption claims against its leader.

He was suspended on Thursday along with secretary general Jerome Valcke and vice-president Michel Platini.

Platini will contest the ban "in the appropriate manner at the appropriate time". All three deny any wrongdoing.

Klaus Stohlker, Blatter's friend and adviser, said: "He has appealed already to Fifa's appeal committee. He is defending his position and he is sure that he will be found not guilty."
