Wales fly-half Dan Biggar says matches "do not get any bigger" than the Six Nations showdown with England on Saturday.
England will be going for the Grand Slam in Cardiff whilst a win over eight points or more for Wales will see them retain the Six Nations title.
"It does not get much bigger than this," said Biggar. "It will be a massive occasion and it will be hyped up by the press this week, but that is great and the way it should be.
"It is a title decider and we are not going to give up our hopes of the title. It remains within our grasp. It will be a difficult game, but one which we are relishing."
Biggar is expecting to be up against Owen Farrell - who has been passed fit for the Millennium Stadium crunch - rather than Toby Flood, who deputised on Sunday and scored all England's points in the 18-11 win over Italy.
"I like Toby Flood as a player. I think he is outstanding," Biggar added.
"But if he is fit, you would think they will go with Farrell because he played well and did the basics well in the first three matches."
Whatever happens, Biggar believes Wales' revival after the opening defeat to Ireland - their eighth straight international defeat - deserves praise.
"Our backs were against the wall after the opening game against Ireland. We had been written off," he said. "To go to Paris, Rome and Edinburgh and pull off three victories is very impressive.
"It is testament to the players and the coaches for sticking with us, and hopefully we have repaid that faith over the last three matches.
"It is nice to be able to reflect on coming out on the right side of those games. Half-time in the Ireland game seems a long way away now, and people have short memories. Not a lot has been written about that game recently.
"I would not have thought, then, we would be in this position going into the final match going for the title, but what that second-half did against Ireland (Wales scored 19 unanswered points) was fill us with confidence after playing some really good rugby.
"As poor as we were in the first-half, I thought we were excellent in the second-half. That gave us the momentum for three gutsy wins away from home.
"If we can come out on top next weekend it will give me more satisfaction than anything."
