Rugby World Cup South Africa v Wales: Win would put us on top of the world says Sam Warburton
Sam Warburton believes it would be "a better achievement" than in New Zealand four years ago if Wales reach the World Cup semi-finals by beating South Africa tomorrow at Twickenham.
Wales arrived at the penultimate knockout stage in 2011, bowing out 9-8 to France after Warburton was sent off.
This time around, though, Wales emerged from the toughest pool in World Cup history, qualifying alongside Australia as England and Fiji were both eliminated, and they have also overcome repeated injury setbacks.
"The body is normally in a pretty bad state after we play them (South Africa)," Wales skipper Warburton said. "It is a really good physical challenge.
"It is just making sure the energy is right this weekend.
"I think it would be a better achievement than four years ago because it has been a tougher route to get there.
"If we manage to get to the semi-finals it would be awesome, purely because in the last World Cup we didn't beat a southern hemisphere team, and that is a target of mine - beating a southern hemisphere team when it matters."
