For granted... but should answers to put Italy away

but it is quite easy to do that at the expense of another area on the same pane of glass.

“The challenge is to get the whole window shining nicely.”

So, can Tipuric do enough as a No.6 to help Wales defend driving mauls? Who is going to make the hard yards if there is a need for someone to tuck the ball under his arm and plough forward? Will it matter that the force of the hits will not quite be the same as it would be with a Ross Moriarty or a Dan Lydiate playing at blindside?

Shake the kaleidoscope once more and a different picture comes into view.

Wales are looking for a bonuspoint victory to chase away the disappointment of defeat in Dublin. The skilful Davies, Tipuric and Faletau have the skills, awareness and athleticism to offer a devastating attacking threat. Instead of worrying about what could go wrong, Gatland will be excited about what could go right.

You suspect the head coach is overloading his long-term memory box with information gleaned from this tournament. Players who put their hands up with stunning displays won’t be forgotten about come the World Cup. Those who consistently underwhelm — well, let’s just say they will have ground to make up, even at this stage.

Opportunities need to to be taken, especially in the front five, where a largely different unit made only a limited impact against Ireland.

Gatland will be keen to see if Nicky Smith has kicked on with his scrummaging.

The Osprey has been superb in the loose for his region this term, offering a ball-carrying presence and proving an unyielding defender while also achieving turnovers.

Not for nothing did Steve Tandy regularly single him out for postmatch praise during the latter months of his reign at the Liberty. But Smith needs to show he is on top of the bread-and-butter stuff at this level.

Italy will look to cut off the supply line to the Welsh backs.

They are no mugs up front, and in the 6ft 4in Sebastian Negri they have a hugely-promising young back rower who beat eight defenders last time out, as many as any Welshman has managed to pass over the three rounds of Six Nations matches.

O’Shea’s team have been trying to play rugby and have scored some nice tries.

But their defence can be porous, especially if the opposition win quick ball.

In Gatland’s ideal world, Wales would devastate them by regularly unleashing bursts of consecutive three-second rucks as New Zealand seem able to do on demand.

Sides can find such passages impossible to defend against but the carrying has to be first-class, along with the support play and ball presentation.

Much attention Gareth Anscombe.

Undoubtedly there will be pressure.

Now-Scarlets coach, Stephen Jones once suggested he felt the same level of scrutiny as a Wales flyhalf that a Brazilian footballer might have felt pulling on the No.10 shirt once worn by Pele.

Anscombe’s attacking prowess is not in doubt, but he will need to demonstrate he knows when to run, pass or kick.

For a fly-half, rugby’s equivalent of shot selection in cricket is the essence of the job. It isn’t just about running everything from the first whistle.

Wales need some control, because the alternative might land a side in trouble against the Dog & Duck.

But it is hard to see anything other than an emphatic home win.

Which is as it should be against a side who have leaked an average of 45 points a game in this Six Nations.

Deep down, Gatland will understand what’s acceptable and he will look to his players to achieve it.

Wales ought to put this Italian side to the sword. will focus on
