FIFA President Sepp Blatter could lose way more than his job -- Swiss authorities are picking up where the FBI left off ... literally digging into Blatter's office to investigate rampant corruption.
Blatter has been accused of criminal mismanagement, misappropriation and making "disloyal payments." Translation: Sepp was allegedly shelling out bribes to other soccer officials, partly to secure TV deals.
Swiss officials said they searched Sepp's office in Zurich on Friday and seized data.
The new criminal investigation comes after the FBI's sting operation in May, which lead to the arrests of 7 FIFA officials. Blatter was untouched in that probe, but no such luck this time around.
As we've reported, Blatter already announced he'll step down after a special election in February.
