Glasgow Warriors boss Gregor Townsend has called for improvement from his charges after they suffered a 23-18 defeat to Leinster at the RDS on Friday.
That result means the champions have now lost three of their five matches played so far this season and they are currently languishing in seventh position in the table.
The Warriors led 13-6 at half-time but were forced to play with 14 men for 20 minutes after Taqele Naiyaravoro and Pat MacArthur were sin-binned during the opening half.
MacArthur's yellow card came in first-half injury-time when he used his forearm in a tackle on Aaron Dundon. Townsend identified his side's discipline as an area which needed to improve.
"Before tonight I was really pleased how we had performed," said Townsend.
"Tonight we just missed those little bits of detail. I'll have to make sure we get those bits right and our discipline has to be much better.
"We had a slow start against Scarlets but showed great character to almost get a win and after that we have played pretty well.
"We almost won in Munster, got a good win against Connacht and got a bonus-point win against the Dragons.
"Against Leinster, in the second half we were down to 14 men for 20 minutes so that's probably why they had more possession and got the points on the board."
