Joe Schmidt and his Ireland coaching staff will be seeking to achieve the very same when they finalise team selection for this Sunday’s Guinness Six Nations trip to Italy.

It is easier said than done.

The Italians are viewed by all as makeweights in the championship, current boss Conor O’Shea having yet to experience victory in 12 attempts since succeeding Jacques Brunel for the start of the 2017 Six Nations, the Azzurri’s championship losing streak having already been at seven when the Irishman came on board.

Yet get selection wrong, as Wales did in Rome for their round two fixture earlier this month, and you are inviting trouble.

Warren Gatland made 10 changes to the side which had come from behind to stun France in Paris in the opening game but the balance was all wrong and Wales were disjointed at Stadio Olimpico, their 26-15 win and the lack of a try bonus point a poor return.

Ireland will be mindful of making similar mistakes with assistant coach Richie Murphy yesterday predicting only limited changes to the XV which overcame Scotland at Murrayfield in round two to rebound from their opening loss at home to England.

When head coach Schmidt unveils his matchday squad, it will reflect that quest for equilibrium.

“The balance is obviously crucial in relation to this week,” Murphy said yesterday. “Making sure our players are getting enough game time, and getting the opportunity to rest when needed.

“It’s probably a week where we have to take the game as is — Italy away is going to be a tough enough test anyway. We’ve to deal with this week, get our formations right to allow us to build into the rest of the championship.”

Murphy does not believe there is too much to separate this current Irish squad in terms of ability and effectiveness for the cause and while he would not pass judgement on Wales’ selection policy two weekends ago, he said: “The squad of players that we have in Ireland, we feel we should be able to put out any of those players and the level of performance should be very similar.

“Because obviously there’s a couple of guys who have come in over this period for the first time and they’re probably learning but a lot of the other guys have been around for a long period of time. They understand what it means, one, to play for Ireland; two, to fit into our systems and be able to take the team forward.

“So the changes in relation to this week, there will be some changes in the team because it’s only natural, that will happen, but I can’t see it being wholesale.”

The position in the Ireland team for Sunday at the forefront of minds yesterday was out-half and the selection decision for the No. 10 jersey represents the difficult art of striking that balance between those opposing forces. With Johnny Sexton fit again after his early withdrawal and failed Head Injury Assessment at Murrayfield 12 days ago, there is the need to give the 2018 World Player of the Year more game-time after just 103 minutes played in 2019 since suffering a knee injury during Leinster’s PRO14 loss at Munster on December 29.

Yet playing the championship whipping boys on Sunday also gives the coaching ticket an ideal opportunity to give a first Six Nations start to Munster’s Joey Carbery, who replaced Sexton, his provincial rival until last summer, on 23 minutes and, after an early wobble, rose to the occasion to steer Ireland home to a vital bounceback victory in Edinburgh.

Murphy yesterday hinted that Sexton will get the start, Carbery perhaps having been given enough minutes against Scotland to mitigate against his inclusion from the start in Rome.

“With all these games it is about getting the right mix on the pitch,” Murphy said. “Joey obviously played a lot of the Scottish game so it is trying to balance that up with game time for Johnny. We’ve watched them training over the last few days. Both guys are in good form. We’ll just make a decision a little bit later on.”

What was unquestionable for Murphy, however, was the progress made by Carbery since his move south from home province Leinster to Munster during the off-season in search of more exposure to life at fly-half.

“I think he’s gone massively in the right direction. All those games that he played at 10 and pressured games, some of them haven’t gone exactly his way and he’s bounced back really well. Obviously Castres away (on December 15), he missed a couple of kicks, come back from them and I think he’s kicked 22 in a row in relation to that part of his game.

“It’s been a massive learning curve. Going in, when he was playing with Leinster, Ross (Byrne) tended to kick and Joey tended to play 15 a lot, so those opportunities have been really invaluable for him and it’s probably a lot of the media have been talking him up as being very much in competition with Johnny Sexton where this time last year we probably wouldn’t have seen that.

“So I think the move has really helped him.”

As for Sexton’s lack of game-time and apparent rustiness since coming back from injury after five weeks out against England on February 2, Murphy said: “Yeah I think that’s the big thing, he hasn’t played a hell of a lot and because of that it makes it tough just to get the feel.

“But the one thing that he’s always been able to do is come in and hit the ground running, so the big thing would be that the Johnny and Joey balance would be incredibly important and what way that pans out this week, we’ll just have to wait and see.

“But Johnny definitely hasn’t played a hell of a lot of rugby and obviously coming off the Scottish game, although he probably actually started really well in creating space for the (Jacob Stockdale) try and a few overlaps on occasions where he was pretty close to actually unpicking them...so it’s getting that balance right, but he definitely hasn’t played enough rugby to be at full tilt yet.”
