Edinburgh coach Michael Bradley admitted his charges had been "embarrassed again" following the 33-0 Heineken Cup defeat to Munster at Thomond Park.
Edinburgh failed to score a single point for the second successive Heineken Cup pool game, and having shipped 78 unanswered points in their two opening fixtures, have seen their hopes of making the quarter-finals all but disappear.
"It is not looking good," admitted Bradley, the former Ireland scrum-half. "At this stage you won't be saying 'no' to qualifying for the quarter-finals...if we win the last four games and get four bonus points and scrape in as the number eight qualifier, which is very unlikely."
He added: "Losing your first two games and getting no points is a recipe for being out of the competition. You have to acknowledge that.
"We are not necessarily worried about winning the Heineken Cup or the Amlin Challenge Cup now, we are more worried about winning the next (league) match against the Scarlets at this stage."
