France coach Fabien Galthie accused Wales' players of making sure Paul Willemse was sent off in Saturday's dramatic Six Nations encounter and urged the authorities not to impose a heavy sanction on the second-rower.
Wales were denied a famous Grand Slam by a last-gasp Brice Dulin try as Les Bleus kept their own championship hopes alive with a breathless 32-30 triumph in Paris.
That was despite France having to play out the final 12 minutes with 14 men after referee Luke Pearce judged Willemse made contact with the eyes of Wyn Jones.
Galthie, speaking through a translator at the post-match news conference, said: "If you watch the Wales players, it feels like they specialise in making sure opponents get red cards.
"Their body language is quite clear, I hope the referees are going to take that into consideration. I don't think he deserves a sanction.
"If you watch the video there is clearly no contact, or if there is it's clearly very limited. It's absolutely not voluntary. I believe we need to share this, I don't see why he should be sanctioned."
Oppositive number Wayne Pivac was keen not to be drawn into a back-and-forth over the incident.
"I don't really have any comment to that," said Pivac. "The match officials are running the game and they have plenty of replays.
"As you saw, it went on for some time. They went through their process and that's what the officials are there to do."
While it was heartbreak in the French capital for Wales, the hosts still have a rearranged fixture against Scotland to play.
To deny Wales the trophy, Galthie's men have to secure a bonus-point win over Scotland and triumph by at least 21 points.
Gael Fickou hopes the best is still to come for France in this year's tournament.
"The pinnacle? I hope it will be next week," the versatile centre said. "Scotland have a great team who are playing very well. We know it will be a complicated match.
"But we will do it step by step. Already, we must try to win it. And then we'll see what happens. We know it will be difficult, but we believe in it."
For Pivac, coming so close to a Grand Slam but falling short left the New Zealander feeling "numb".
"[It's] just desperately frustrating. The players got so close. We have to be proud of them," Pivac added.
"It's quite a numb feeling. The boys had put in such a fantastic effort, the game went pretty much to plan in the first half.
"We were urging them on, but to go from a potential Grand Slam to waiting another six days is frustrating."
