Former FIFA president Sepp Blatter to attend CAS hearing today

"I am not corrupt. And if someone says it, let him prove it."

Former FIFA president Sepp Blatter's fate hangs in the balance as the Court of Arbitration for Sport hearing into his six-year ban gets under way on Thursday.

Blatter's 18-year run at the head of world football's governing body ended acrimoniously last December when he was banned from the sport for eight years, later reduced to six, by the FIFA ethics committee.
