Wales coach Mike Ruddock has urged his team to avoid the 'flat spots' on their continued ascent towards the RBS 6 Nations summit and possible title glory.
Ruddock's unbeaten entertainers face possibly the biggest test of his nine-month reign this weekend - France in Paris.
And despite recording impressive victories over England and Italy earlier this month, Ruddock believes there is more to come from a Welsh side whose ravenous appetite for running rugby has won worldwide plaudits.
"We've had a tendency to hit a couple of flat spots in the games against England and Italy," he said.
"We had a great first half against England, perhaps we should have scored a couple more points, then hit a flat spot just after half-time and let them into the game a little bit.
"And in the last quarter against Italy, we hit a flat spot and gave away five penalties. We've got to try and get those flat spots out of our game.
"We've got away with it so far, but against a side like France, if we start giving them penalties, we could be in trouble."
Wales have never won the Six Nations Championship, and their last Five Nations title success was achieved 11 years ago.
But expectancy is growing in Wales after Ruddock's men saw off England for the first time in Cardiff since 1993, and then ran Italy ragged at Stadio Flaminio.
"At no time, within the camp, have we talked about winning championships, Grand Slams or Triple Crowns, we just haven't done that," Ruddock insisted.
"It is going to be a difficult challenge for us on Saturday, but the boys are up for it.
"We believe in our style of rugby, there is a great team spirit and we've got the players, we believe, if they put their game together can do very well in Paris.
"We try not to talk about the pressure, we just try and talk about the game plan and the way we want to approach the game.
"This team hasn't played fully for 80 minutes, to its maximum potential yet, so while we are quietly confident that we can get a result in France, we know that we need to improve our game."
Saracens director of rugby Mark McCall believes Alex Lozowski has only just scratched the surface of his potential after the 23-year-old celebrated his England recognition by scoring a try-double against Bristol.
