"We won today, but we haven't forgotten that only six players paid for our collective failure," said the former captain. "Anyone of us could have been one of those six that had to leave."
Captain Thierry Dusautoir was delighted to be back to winning ways. "I'm happy for the team, and also happy for the management, especially after this hard week.
"We deserved that tough week after the result in Italy. I'm happy with the way we bounced back."
