Shane Williams thinks there is plenty more to come from Wales' Grand Slam heroes, claiming they won the Six Nations title in "third gear".
Things are looking pretty good for Warren Gatland's side at the moment, having secured a Six Nations clean sweep last weekend with a record 14th consecutive win.
But Wales' record try-scorer is adamant we haven't seen the best of this Wales side as thoughts already turn to the World Cup later this year.
"I said from the start of the tournament, we haven't seen half the potential of what Wales can do this year," said Williams.
"They won the Grand Slam in third gear.
"They just look so comfortable even when they were down at half-time against France or England. Three years ago, you'd be thinking we'd lose it.
"Now you just think we'll step it up and get back into it. If I'm not panicking, then the players aren't.

"They look like a team that really don't to lose and think they're too good to be losing these games.
"Sometimes the top two inches are all you need and they certainly have the mental toughness at the moment."
And it's that mental strength and the added depth that Williams believes separates the current crop from the hugely talented side that won Gatland his first Grand Slam with Wales back in 2008.
Williams played a crucial role in that team, scoring six tries to help record the first of Gatland's four Six Nations titles.
"2008 we did particularly well. I look at the team that was on the field and we had a class, class side," added Williams. "Some real world class players.
"Stephen Jones, Martyn Williams, Gavin Henson, Lee Byrne, Mike Phillips, James Hook. That starting XV were worldbeaters. We could take on anyone.
"But then I look at the squad and the players not quite making the side and I can tell you for certain we had nowhere near the strength in depth this squad has now.
"We had nowhere near the confidence and self-belief this squad has now.
"Every time we played, we were fearful of losing. This team doesn't fear losing because they know they can play 80 minutes and if they are tired, there's a class player coming on for them.
"And I don't think we had that.
"I don't panic when Anscombe goes off because Dan Biggar comes on. I don't worry when North goes off injured because we have players to cover.
"We have world-class in abundance in the back-row, while in 2008 we may have had Martyn and Ryan Jones, but did we have the options like Gatland does today? Probably not and I mean that respectfully.
"This squad is probably the strongest Welsh squad I've ever seen. We've seen in games that people off the bench can win games.
"The All Blacks can put any team out and Wales are getting there. They're becoming a team who can win games with players who we maybe didn't even realise were good enough to get in the team.
"But they play their hearts out for their country and for Warren."
Before the World Cup, there's the small matter of the end of the PRO14 season - although it's looking unlikely Williams' former region, the Ospreys, will be able to mount a late push for the play-offs or Champions Cup qualification.
However, after much uncertainty, the region's immediate future is safe - something Williams describes as "hugely important" after seeing how much recent events have "taken their toll on the players".
Now the future of the Ospreys looks a little clearer, what do the west Wales region need to do to reclaim their crown as Wales' premier side?
"What the Ospreys have got to do is finish the season strong", insists Williams. "Whether they can qualify for anything or not doesn't matter, it's about showing the fans you want to remain at the Ospreys.
"It's about digging in and showing some character. They've had a terrible 12 months, a really horrible three or four months, but let's turn it around.
"You want those players to be positive after such a hard time and show they want to be Ospreys going forward. Hopefully the little bit of clarity will help."

Does Williams place the blame at the feet of head coach Allen Clarke?
What about the work of attack coach Matt Sherratt, with the Ospreys having struggled creatively this season?
"The politics of the season hasn't helped Allen Clarke," says the 87-cap former international. "It's been a bit up and down. I look at their backline. Keelan Giles, Hanno Dirksen, Luke Morgan, George North, Scott Williams, Owen Watkin.
"I remember thinking this could be one of the most potent attacking threats in the PRO14 but it hasn't happened.
"Whether that's Allen Clarke or Matty Sherratt, I don't know. I don't think it is, I think the politics haven't helped.
"I've heard so many good things about Sherratt and he's clearly a good attack coach.
"But we should expect more. I don't think they know how they want to play.
"Some players get frightened to attack in teams like that. They just need to chuck it around a bit in these final few games.
"We're getting left behind by regions who don't have the attacking threats we have.
"For me, the important thing is how Clarke responds to all this and finishes the season. I think he needs to learn his lesson about sending young squads to places like Munster.
"There's nurturing players and then there's sending kids who aren't ready to the best sides in Europe on a hiding to nothing.
"But having spoken to players, he's a good coach but he's had bad stuff happen around him. He has to take some of the blame because, ultimately, it's been a poor season."
