Blatter, who has been in charge of the organization since 1998 and won re-election for a fifth term Friday despite allegations of mass corruption within FIFA, announced at a press conference in Zurich that he would step down after a special congress is called between December and March to appoint his replacement.
Treble is used in association football to refer to a team winning three trophies in a single season. Honours usually considered to contribute to a treble are the top-tier domestic league competition, primary domestic cup competition and most prestigious continental cup competition, although this depends to some extent on the football competitions of a particular country.
It seems to me, given that it's only occurred in South America once, and that was over 50 years ago, and oh, by the way, that team had Edson Arantes do Nascimento on the roster, the answer must clearly be that the South American triple is the most prestigious of them all.
But Saturday's game should still be fun!
