Ulster head coach Mark Anscombe wants improvememt from his side after Friday's 41-17 Heineken Cup win over Castres at Ravenhill.
It took a last minute try from replacement scrum-half Ruan Pienaar for the Ulstermen to secure maximum points from the match. This after left wing Andrew Trimble and starting scrum-half Paul Marshall's brace earlier.
Despite the convincing win, Anscombe believes his team's overall performance was not clinical enough.
"That's what we set out to do (get a bonus-point win) as I said to the guys we had to set out to achieve that and we did," he said.
"But we know we've got a lot to do and we've got to do it next week. But we achieved what we needed to do tonight.
"It might have been fortunate but we did it. Our execution, though, became a bit too loose at times."
It took almost 20 minutes for Ulster to clinch the bonus point with Pienaar's try and Anscombe admitted that he was concerned about how his team went about claiming much-needed final score.
"We were trying to force it but it wasn't happening; it got messy and our option taking was poor," he said.
"We scored some good tries and played some good rugby but we just got too loose.
"They got into us a bit and started taking the breakdown ball and we didn't look after it so it became a messy affair."
