I don't think any of this is about sour grapes.
It is all about fair play. There is a difference. Had we lost fairly and we complained that would be sour grapes.
If someone steals your wallet, is it sour grapes to complain? That's what some of the forgive and forget folks make out.
Anyways, the hypocrisy of FIFA is pretty blatent. It is a sham of an organisation, a mickey mouse institution. The WC will be more like EuroDisney than a serious football competition because of FIFA.
