Tensions are clearly running high at Racing-Metro after team-mates Jonathan Sexton and Juandre Kruger had to be pulled apart following a training ground altercation on Tuesday.
The pressure is on the Parisian club ahead of Friday's Top 14 play-off away to Toulouse.
Racing were the in-form team of the second half of the French season and were on course for a home knock-out fixture until Saturday's 44-10 thrashing in Montpellier pulled the handbrake on their ambitions.
At training on Tuesday, the light-hearted camaraderie of recent weeks was replaced by stern faces and an intense workout.
During a contact session, Ireland fly-half Sexton reportedly screamed in the ear of Springbok lock Kruger for what he believed to be excessive physicality at a ruck. The former Bulls second row did not appreciate the Irishman's attitude and the duo had to be separated by their team-mates.
"We're preparing for a big match in Toulouse and there is obviously a lot of pressure and aggression," French international loose forward Bernard Le Roux told Rugbyrama.
"We arrived in Montpellier very confident after our five straight wins, but lacked desire and that hiding we got probably did us good.
"We must be more focused and precise this week because we do not want the same game as on Saturday. "
On the training field, co-coach Laurent Travers was barking the orders.
"On Friday, we have to get in their faces," he shouted at his players.
Centre Henry Chavancy was pleased with the intensity he saw in the session.
"I think if there is no commitment in a finals week, there never will be," said Chavancy.
"We saw a lot of commitment and desire in this session which is very good.
"We didn't get it right in Montpellier and we can only blame ourselves. We must double our efforts this week to go to Toulouse and give it all we've got."
