Wales head coach Warren Gatland believes that his team struggled in the final 20 minutes of their defeat to England on the opening night of the Six Nations.
The hosts produced a fast start, opening up a 10-0 lead and reached the interval eight points ahead, before England scored 13 unanswered second-half points to take victory in Cardiff.
Gatland has admitted that Wales started well, but finished the game on the back foot.
He told BBC Sport: "I think it was the third quarter that hurt us the most. It was a tough, tight Test match. You've got to give England credit.
"I thought we started well and looked comfortable at half-time. There's seven months to go to the World Cup. Even had we won today it wouldn't have meant a huge amount in regards to seven months' time. We've lost the first game of the Six Nations and we have to get back on the horse."
Wales have been drawn in the same group as Australia and hosts England for this autumn's Rugby World Cup.
