Colin Charvis admitted the impressive opening RBS 6 Nations Championship victory against Scotland does not in itself constitute a Welsh rugby revival.
And the national team skipper conceded that Ireland in Dublin on Sunday will prove a far bigger examination than that posed by an unfamiliar Scotland side just starting its regeneration under new coach Matt Williams.
"The real test is going to be whether we can put in another performance a week later. We are renowned for playing well one week and then falling apart the next," admitted Charvis.
"Ireland have had a defeat in Paris and I am sure they will be desperate to avenge that.
"Playing them at Lansdowne Road is always very difficult, but as long as we analyse what went wrong and what went well for us here, work hard and have a good week of training, we can then build from there."
Charvis insists the Welsh players are certainly not getting carried away following their 23-10 win at the Millennium Stadium in Cardiff.
"There is no chance that a lackadaisical attitude will fall into our camp or that we will get over-confident," the Wales captain maintained.
"We have got to live up to the expectations we have hung on ourselves.
"We had a good performance in the World Cup and have won this match, but that is by no means what we are going to settle for.
"We have worked very hard for a very long time and we want to build on that."
"I am sure that by the end of the tournament we will know our level, but at the moment we just want to keep getting better."
