International Olympic Committee president Jacques Rogge has encouraged ''a cleanout'' of Fifa during discussions with the football president Sepp Blatter
Dr Rogge said he had spoken to Mr Blatter in recent days and hoped that Fifa becomes a more transparent organisation.
He said the IOC had to remain vigilant to corruption, even though the Olympic Movement had a painful reform processs in the wake of the 1998 Salt Lake City bribery scandal.
''I encouraged him to do what he has done and clean out as much as possible, we have been through this... and the IOC came out as a better and more transparent organisation and I hope that happens to my friends.
"Will this happen again to the IOC? I hope not, we have the processes to protect us as much as possible, but cheating is embedded in human culture, we are very vigilant, we have strict rules and I believe this protects us as much as possible, but you can never say never.''
