It's a lot more sordid than that.
The presumption within FIFA was that Blatter would stand aside and allow Platini to replace him in 2015, which is why Platini was toeing the party line for the last election by asking the UEFA nations to back Blatter for his (unopposed) re-election in 2011. Now that Blatter has done a u-turn and says he will stand for re-election next year, it's no wonder that Platini is no longer backing him - because Blatter has stabbed him in the back by reneging on their deal, and he's done it with less than a year before the election which has scuppered Platini's plans.
The question is what does Platini do now: does he stand on his own, or does he throw his influence behind Jerome Champagne's bid?
Isnt that similar to what happened between Tony Blair and Gordon Brown?
