Munster boss Anthony Foley called on his side to show some character after their disastrous loss to Stade Français.
Despite having a man advantage for the whole of the second half after Josaia Raisuqe was shown a red card, Munster were well beaten in Paris.
Foley called on the group to carry out some serious soul-searching and to produce a response for their supporters next weekend in the reverse fixture at Thomond Park.
"It's disappointing, there were opportunities in the second half that we didn't execute. We didn't play and we didn't score, they held us at nil for long periods," Foley said.
"We never really put pressure on them and never took advantage of the extra man and we suffered the consequences.
"We need to look within, deep down like we always do and come up with a solution. We need to dig deep and come up with our own answers, their will be people out there with solutions, but we need to come up with our own solutions.
"We need to turn up for our supporters next week and put on a show. It's about showing our character, showing who we are and showing who we represent.
"We're all disappointed, but it's about showing our true character."
