Alan Quinlan has described Munster's performance in their 27-7 defeat to Stade Francais this evening as 'borderline disgraceful'.
Anthony Foley's men were run ragged in Paris by a French side that had only 14 men on the pitch for most of the game.
With two games left in their Champions Cup pool, the defeat means Munster cannot progress to the knockout stages, and their former back row player was exasperated by them.
Quinlan said: "I am trying to think of words to sum it up.
"Embarrassing, disgraceful, humiliating - all those words come to mind.
"Munster have no divine right to win these games but this is embarrassing and this whole organisation needs to be dissected now. They need to look at the structure from the top to the bottom and figure out what is going wrong.
"They are lacking a bit of talent - there is no doubt about that - but when a team plays with no spirit, no heart and no passion then that really upsets me. As it does all the Munster fans who follow them all over Europe.
"It was borderline disgraceful - maybe it's a bit extreme to say that performance was disgraceful, but guys falling off tackles, no desire, no structure and no shape - and it was really upsetting stuff."
