Leicester Tigers director of rugby Richard Cockerill said it was a case of "job done" as his side secured a much-needed bonus-point victory against Treviso.
Tigers ran in five tries on their way to a 33-25 win in their Heineken Cup clash at Welford Road, which sees them leapfrog Ospreys into second place in Pool Two, three points behind Toulouse.
Julian Salvi was the star of the show for the hosts, scoring two of his side's tries alongside ones from Manu Tuilagi, Matt Smith and a penalty try.
But Tigers were left hanging on in the second period as Treviso got to within eight points and left the Welford Road faithful holding their breath.
That prompted Cockerill to fire a warning to his players not to be complacent when they make the trip to Italy for the return fixture at the Stadio di Monigo on Saturday.
"We started well, we scored four tries and we were trying to play," he said.
"But we only have ourselves to blame in the second half, we were inaccurate and, if you can't catch and pass, then it's a problem.
"We just went to sleep. To be fair to Treviso, you have to say they played pretty well and more than played their part. It was a lot closer than we would have liked, but it's job done, it's five points.
"We made a raft of changes quite early in the game so we could protect the Test guys, but it certainly won't lead us to be complacent this weekend, so maybe it's done us a favour.
"I don't think we were complacent. I don't think we were under any illusions as to how good they (Treviso) were – two years ago we nearly lost there in the first round.
"The players will certainly know they're in for a tough match. We have to go back to Treviso and try to get five points. Whether that's attainable we'll have to see, but there is no guarantee that it will be a given.
"Hopefully, we won't play as badly as that. We need the win first and foremost, but five points would be very helpful."
Tigers welcomed back five of their England internationals, with lock Geoff Parling captaining the side alongside Tuilagi, Ben Youngs and brother Tom, who all returned to the starting XV with Dan Cole an unused replacement.
"They are all fine and there are no major injuries with them," said Cockerill. "So it's job done, no more than that."
