Leinster coach Michael Cheika admitted is team got what they deserved and he took responsibility for the outcome of yesterday;s 29-10 Heineken Cup defeat to Edinburgh in Scotland.
He said: "Murrayfield has not been a happy hunting ground for us, but it is nothing to do with the venue - it was the standard of our rugby.
"Our discipline as poor in the early stages and that took the initiative away from us. We never really recovered. The penetration was not there and our decision-making was not up to scratch.
"The Heineken Cup is a tough competition and we are in a tough group. The reality is that if you don't perform, you don't make it."
Cheika refused to hide from the blame after his side's defeat.
He added: "It is my responsibility to make sure we play good football and that didn't happen. We did not win the key battles out there and I feel for our fans who made the journey to back us."
Simon Webster and Ben Cairns got the Edinburgh tries with Phil Godman kicking both conversions and four penalties. Mike Blair also kicked a drop goal.
Felipe Contepomi converted Leinster's penalty try and also kicked a penalty.
Edinburgh supremo Andy Robinson could not hide his elation after watching his revitalised players break their Heineken Cup duck.
And he tipped his young squad to build on the 29-10 success and emerge as a potent force on the European stage.
The former England coach said: "I can't praise my guys highly enough for the efforts they have put in over the past few weeks and this result is no more than they deserved.
"We are now proving we can compete with the best teams in the competition and the aim is to keep progressing.
"The workrate and positive attitude of the players has been professional in every sense and I am genuinely excited over what these guys can achieve in the future.
"We can now look ahead with increasing confidence to our remaining pool matches against Leicester and Toulouse and our Magners League campaign."
