After the IOC said they would investigate allegations of corruption by FIFA members, Blatter said: "Our accounts are open to everyone. The IOC does it like a housewife. She receives some money and she spends some money.''
Blatter’s latest comment will stun many angered at alleged corruption against FIFA members, not to mention the shock decisions to award Qatar the 2022 World Cup.
One of those FIFA members accused of corruption by the BBC Panorama programme - Cameroon's Issa Hayatou - is also an IOC member and, while Blatter claimed there was no case to answer for, the IOC promised a full investigation by its ethics commission.
The IOC has had problems with corruption in the past but they have largely been rubbed out after the Salt Lake City scandal in 1998.
The IOC found that several members had taken bribes to secure Salt Lake City the 2002 Winter Olympics and, while no criminal charges were brought, 10 IOC members were expelled and another 10 sanctioned.
There were also major changes made to the Olympic bidding process including forbidding IOC members to visit bidding cities as well as stricter regulations on IOC membership.
This is in stark contrast with the murky world of FIFA hustings, where a small number of delegates vote in secrecy amid shady lobbying by competing bid teams.
