Sepp Blatter to FIFA -- I Quit This Bitch

Sepp Blatter has officially resigned as the president of FIFA -- after an FBI sting operation into the organization that led to the arrests of 14 FIFA execs.

Blatter says he will spearhead the search for a replacement.

Blatter ran for reelection and WON last week -- but says he now believes he is not getting the support he had hoped for from the international soccer community.

In a statement to the media, Blatter said ... "FIFA's interests are dear to me. That’s why I have taken this decision. What counts most for me, is the institution of FIFA and football around the world.”
