Leave it to Sepp Blatter to bring new meaning to the phrase “the least he could do.”

The day after the FIFA scandals reached his very doorstep, the long-term international soccer head announced he’d quit . . . in a few months, after carefully guiding the process to choose his replacement.

Sorry: FIFA under any other hack will reek just as much.

News broke Monday that Blatter’s No. 2 knew of the $10 million payment to a just-indicted official, which investigators say was a bribe. Blatter had to step down.

Of course, that FIFA didn’t vote him out last week, in the wake of the Justice Department’s 47-count corruption indictment, is proof the place is pervasively corrupt.

And the scandal is still metastasizing: Tuesday’s news was that the FBI has its sights set directly on Blatter.

How to clean a house as dirty as this?

Blatter’s immediate exit, and that of all his cronies — and even his putative foes — seems a minimum. FIFA needs new management, top to bottom — all from outside, and fully vetted for integrity.

The place is so corrupt, even that might not be enough.
