Gloucester director of rugby Dean Ryan insisted it was a case of "job done" after a scratchy European Challenge Cup win in Bucharest.
Gloucester ground out a 27-13 victory over a winless Bucuresti to ensure quarter-final qualification, and Ryan paid tribute to the home side.
"I thought Bucuresti played outstandingly well and that is a great credit to them," he said.
"From our point of view, there was a quality issue but I thought we adapted well and got the four tries and the bonus point.
"It was a difficult environment but we came here and got a job done and that’s the most important thing."

Gloucester moved up a gear in the second half with tries to hooker Rob Elloway and replacement scrum-half Peter Richards, before a late penalty try ensured a bonus point.
