Auckland, North Island
They say there's a thin line between genius and madness. If that's true, has spent this World Cup tip-toeing along it like his compatriot Philippe Petit in Man On Wire.
On one hand he has steered an underperforming French side to their . On the other he has done so while spitting out the sort of insults that normally start wars.
In a moment, the question of whether the latter has made the former possible. Before then, a little reminder of Marc's most barking bon mots.
To French journalist after pool stage loss to All Blacks: "Go to hell with your question. I really regret the detestable atmosphere that we have at these press conferences."
After pool stage defeat by Tonga: "I thought I had experienced everything in terms of shame. But this time around, it's been an extremely violent feeling again. Each missed pass, each missed tackle, I took them as a deep personal failure."
On his attempts at team-building: "I would have liked for us to gather around a few drinks yesterday, to talk, to share thoughts, to tell each other that it's a beautiful adventure, all things considered. And I was disappointed.
"At the end of the press conference, I got us some beers to release the pressure - and we all split in different directions. I saw players with their agent on the eve [of the match] and after the game instead of regrouping as a team. It's a kind of disappointment."
After defeat by Italy in the Six Nations: "I'm at a bit of a dead end. I feel like I'm responsible for this, but the players lack courage. There is a certain cowardice. When I talk to them, nothing happens.
"They betrayed us, they have betrayed me and they have betrayed the French national team shirt. Do you really think I told them to play like that? They weren't asked to walk on the moon."
On former England hooker Mark Regan: "He was ridiculous and grotesque. His behaviour is offensive and against the rules. He is a clown."
After beating England in the quarter-finals: "Yesterday we had the same players out there as in Wellington against Tonga, except that they grew a big pair of balls."
After some players went out drinking following their win over Wales: "I told them they are a bunch of spoiled brats. Undisciplined, disobedient, sometimes selfish. Always complaining, always moaning. It has been like this for four years."
