Martyn Williams says Wales must seek to improve despite running Italy ragged in Rome to secure their first back-to-back wins in the Six Nations for 11 years.
The Blues flanker scored a try and was involved all over the pitch in the 38-8 victory, winning man-of-the-match.
"Last week was a big win against England but we had to take that on - and we did against Italy," he said.
"But despite the six tries we were quite scrappy and we have a lot to improve before going to France."
The Italy pack caused their visitors plenty of problems in the Stadio Flaminio, but the Welsh forwards slowly turned the tide to gain the upper hand.
"It was a magnificent effort by the front five to give us the platform we needed to play, not just in the scrum, but at the line-out and in loose play as well," Williams added.
Wales coach Mike Ruddock admitted to a few nerves before the match, but was delighted with the way his side settled to their task.
"As confident as we were, you realise that this could have been a bit of a banana skin and we needed to be quite clinical to get the result," Ruddock said.
"I asked the boys to start well and don't make the mistake that perhaps Ireland did last week by letting the Italians come at them.
"We scored first, obviously the charge down (Italy fly-half Luciano Orquero blocked Gavin Henson's kick to score) let them back in.
"But we didn't panic and eventually came through with a bit of style."
