Jamie Roberts reflected the mood in Wales' World Cup camp by warning there is no time to dwell on their shattering Springboks loss.

The giant Cardiff Blues centre produced his best display since starring on the 2009 British and Irish Lions tour of South Africa.

But not even Roberts' scintillating display could give Wales the win they so badly wanted as South Africa prevailed 17-16 after Morne Steyn converted substitute Francois Hougaard's 65th-minute try.

“Sport can be very cruel times,” Roberts said.

“When you lose by one point to the world champions in your opening game of the World Cup, it's a bitter pill to swallow.

“It's heartbreaking. The changing room was a very sombre place. But it was a game we should have won.

“But this tournament is too short to dwell on a result like that, and we need to take the positives from the game.

“We just need to pick our heads up. It is a week's turnaround until we play Samoa, and we need to win our other three games against Samoa, Namibia and Fiji.” Tweet
