Wales coach Steve Hansen was delighted with his side's first half performance in the 23-10 win over Scotland but he wants them to maintain their momentum for the full 80 minutes.
"We got away to a good start but the second half was a bit scrappy really," he said.
Wales maintained their momentum from the Rugby World Cup, and Hansen said: "We dealt with the expectations all week and the players had enough confidence in themselves and each other. We had good preparation and Saturday is the fun time.
"With a little bit more composure we could have scored a couple more tries.
"In the second half we lost our shape and our line-out but that is all credit to Scotland. If they are the benchmark when it comes to line-outs we need to rise above that."
Hansen is certainly not getting carried away with one performance and he said: "I don't think anyone is jumping up and down and going through hoops at the way they performed.
"But it is 1997 since we won in the first round of the Six Nations and I think we enjoyed that moment.
"We are reasonably happy with the style we've got but we just need to be more accurate with it for longer periods. If we get it right then it is hard for teams to combat."
