Unless Mikko can push the Citroen team orders to wait for last stages of GB, there is no real chance for Ogier to break them. But for that situation to even occur is quite unlikely, and one rally in between, so not much point to discuss.
Though I think it's a very valid speculation to question if Quesnel is really done and over with his agenda... Is he playing a two-face for both the media and the PSA management? It's still Quesnel-Ogier vs PSA-Loeb as far as I'm concerned. And due to what happened in France, which btw still smells, the whole thing is wide open.
You can't dictate Loeb to walk away with this one.. I think he will rise to the challenge, but he can't afford a moment of bad luck, and he hasn't had this type of pressure ever before; Both from the outside and inside of his team, even with 2 drivers at the very end of the season. If he can't close in next behind Ogier in Spain, so they can swap positions, then Ogier has a very real chance to snatch this title.
