Shaun Edwards has warned Ireland that they will face a tougher test when Wales travel to Dublin later this month.
An experimental Red Dragons side suffered a 35-21 defeat on home soil this weekend in their opening Rugby World Cup warm-up clash.
Despite the heavy loss, defence coach Edwards believes that by the time the reverse meeting comes around on August 29, his side will be in a far better shape.
"We were never planning to peak on August 8 in a rugby sense," he told BBC Sport. "It probably would have been a little bit different if we had played a more experienced team. Come the return fixture, we would like to think we will be a lot more competitive."
Wales handed debuts to Eli Walker, Tyler Morgan, Ross Moriarty and Dominic Day in the Millennium Stadium defeat.
