British and Irish Lions stalwart Jamie Roberts believes the side's victory in Australia can spur Wales on to World Cup glory.
The Racing Metro-bound centre played a pivotal role - and scored one of the tries - in the Lions' 41-16 win in the third Test against the Wallabies in Sydney last weekend.
That result secured the Lions' their first series win since 1997 and only their fifth ever series triumph over Australia.
Roberts was one of 11 Welshmen who were in action last weekend and he believes that their fine performances on the Lions tour will be a boost for Wales.
"Obviously I am moving to a new club, but the next goal now is to move into the autumn and really challenge the southern hemisphere teams as an international side with Wales," he told Walesonline.
"We really move forward now in the next couple of years towards the World Cup.
"Having seen how the Welsh guys have performed on this tour, it is hugely promising looking forward to 2015. We want to win the World Cup.
"To see how many people have turned up to support us, it is pretty special," the 26-year-old said.
"It will probably take a few weeks for it to sink in for what we have achieved in Australia.
"For all 80 people on that tour, it is something to savour for the rest of our days. We made history.
"Ultimately, not many Lions tours are victorious, especially over the last 50 or 60 years.
"We are very proud of that and hopefully the boys can enjoy a good off-season now over the summer and just really reminisce for what we have achieved."
