Investigators turned up evidence of tax evasion, kickbacks from multi-million dollar transfers of players to Europe and even money-laundering.
Press interest in pushing the investigations further would almost certainly be fuelled by another World Cup defeat - even if the Brazilian team gets to the final.

At present many top clubs are facing bankruptcy - unable to pay their players.

"But football is not in the blood of the people. They don't deserve to win. They don't know what to do with the World Cup."
