"It's been the story of our season so far," O'Driscoll said after the match.
"I don't want to dwell on it any more than that. I've been saying that for the past 11 weeks, but it is difficult to keep on saying it.
"We've maintained our level of performance which is pleasing.
"It's the same old problems occurring where we've failed to defend a set piece as well as creating chances and not being able to score them."
