Two teams in contention for the Six Nations title - England and Wales -- lock horns in an as-good-as-it-gets rugby Test of the Six Nations at Twickenham on Sunday.
Both teams have won two of their three games in the tournament so far, and after seeing both Ireland and France grab victories on Saturday, neither team will want to end up on the losing side.
England will have the home advantage, but Wales the psychological one, having beaten their neighbours in their last three matches.
"It's a big game psychologically for both teams because we have to go there next year as well," said Wales coach Warren Gatland, who won his first match in charge of his team at Twickenham. "That's going to be even bigger than this Sunday.
"We have two big games at Twickenham in the World Cup against England and Australia. But, if we can win on Sunday, that's four in a row against England and if we then win the Six Nations' as well you [opposition] start having a few doubts."
Wales bounced back from a heavy defeat to Ireland in the second round, with a professional win over France at the Millennium Stadium a couple of weeks ago, and Gatland, who will be without Luke Charteris with a neck injury, with Luke Ball stepping in, will be keen to see his side carry on the momentum.
"After a disappointing performance against Ireland I thought we played exceptionally well against France," the New Zealander added. "What pleased me was the maturity we showed particularly in closing the game out after being up at halftime.
"Part of my job for this week is to build the players up to have the self-belief that we are good enough to go to Twickenham and win. It has definitely been a bridge too far for a number of Welsh players in the past but we're not thinking like that. We won there two years ago.
"They [England] are all saying they have learnt some pretty harsh lessons from last year. All the talk is that the boys have turned into men and they have grown up and learned. Time will tell, won't it? We'll see on Sunday."
For England, fresh from that big win over Ireland in the previous round, it is about moving one step closer to that elusive silverware, as Stuart Lancaster also looks for his first win against Wales as coach.
"All the talking is fine but we have to make sure we deliver on the field," said Lancaster, who chose Ben Morgan as a replacement for the injured Billy Vunipola. "It's a big game, a tough game, but we think we're ready. Looking at the quality of their team, they are full of British Lions. We don't have so many but, come the day, let's see what happens.
"We respect them and they have got more to their game than people give them credit for. The gain line is important but I'd be surprised if they don't have a few tricks up their sleeve as well.
"We have an opportunity to play against a team that is strong in lots of areas. We have a chance to test ourselves."
