Edinburgh coach Andy Robinson has slammed his side - which contained 10 Scotland regulars - for their defensive deficiencies against Leinster in the European Cup.
The Irish province ran in four tries at Murrayfield as Edinburgh's European Cup campaign got off to the worst possible start.
Australia star Rocky Elsom, 2005 Lions captain Brian O'Driscoll, Argentina centre Felipe Contepomi and Ireland winger Shane Horgan all crossed in the first half as Leinster won 27-16.
All Edinburgh could offer in reply was a penalty try and 11 points from the boots of Chris Paterson and Phil Godman.
Robinson said: "It was very disappointing. We certainly have to understand how to tackle. The first-half tackles that we missed were poor.
"Leinster hadn't really created anything, they just broke our line and scored four tries just from unstructured play. Credit to them for their support play.”
