Another convincing win for Ireland has thrown up further selection dilemmas for Joe Schmidt and his coaching staff, as they are left to ponder who to select for Ireland's crunch World Cup clashes against Italy and France.
We have identified the positions most likely to keep our Kiwi coach up at night.
The back three
This one is surely going to give Joe Schmidt and fans alike a major headache, as all available options seem to be in sparkling form.
Keith Earls was awarded the Man of the Match award today after dotting down twice and dancing around defenders for fun.
Earls equaled Brian O'Driscoll's Rugby World Cup try scoring record (7) for Ireland with his two trys today, and on current form looks almost undroppable. Tommy Bowe resumed normal service after his horror-show at Twickenham during the warm-up games, also grabbing a double with the first being a world-class finish.
And then there is Simon Zebo, who put in another top-drawer performance with three assists - and he was desperately unlucky not to have a try of his own. Luke Fitzgerald is also right in the mix, carrying good form into the tournament.
Let's not forget Dave Kearney, who was the surprise inclusion in the squad but has been the form winger over the past couple games, with a big performance against England and then scoring last week against Canada.
Rob Kearney came off the bench today to score, and barring injury, the 15 jersey will be his. That leaves us with the two wing spots up for grabs between Earls, Zebo, Kearney, Fitzgerald and Bowe.
Bowe has a wealth of big game experience; Earls and Fitzgerald can be scintillating on their day; Kearney is a Schmidt favourite for his work rate and athleticism; while Zebo offers pace and a playmaking ability outside of Johnny Sexton, as we saw today.

Considering the likes of Andrew Trimble, Felix Jones and Fergus McFadden remain at home, it shows the unprecedented level of strength and depth Ireland currently have at their disposal for the back three positions.
Second row
Another area of the pitch where Ireland have strength in depth, the competition is fierce for the second lock position alongside Paul O'Connell. This looked a straightforward decision three months ago as Toner and O'Connell were Schmidt's preferred pairing, but the form of Iain Henderson in recent weeks and Toner today has left us with another selection dilemma.
Ulster lock Henderson forced his way into the starting line-up with his aggressive and abrasive style of rugby, winning him many admirers. Toner and Donncha Ryan got their chance to impress today and impress they did as Ryan went through a huge amount of 'ugly' work, hitting rucks with aggression and tackling well, but it was Toner who will be firmly in Schmidt's mind for selection.
The 6'10 lock did the basics right and was a significant weapon from set-pieces, claiming line-out ball as well as an Ian Madigan restart. Given how reliant Ireland are on their set piece play, Toner may just be ahead of Henderson in Schmidt's mind.
Henry or O'Mahony
Asides from the half-back, the back row combination has been the most settled area of Ireland's team for the past season or two. Jamie Heaslip, Sean O'Brien and Peter O'Mahony are normally among the first names on the team sheet, but after another excellent performance from Chris Henry, Schmidt may just well be re-evaluating his options.
As always the Ulster flanker was a massive presence at the breakdown, with his groundhog like stance securing quick ball for Ireland and proved to be a nuisance for Romania at ruck time. It is unlikely that Henry will displace O'Mahony on today's performance alone given the quality of the opposition, but he is a proven international-class flanker and is a more than able deputy.
Henry capped off a fine performance with a try from the back of a maul.

The battle for the bench
Things are tight across the squad, and while there may not be too many places up for grabs in the first 15, there is fierce competition for places in the matchday 23.
Richardt Strauss put in another strong performance today and is locked in a battle with Sean Cronin as back-up to Rory Best, though the Limerick mans explosive impact from the bench may edge out the naturalised South African. Ian Madigan finally looks to have cemented himself as Ireland's second choice out-half but Paddy Jackson looked very assured today when he came on.
Two men on the opposite sides of their playing career's are battling it out for that pivotal reserve tight head spot, with 34-year-old Nathan White looking to have the edge on 22-year-old Tadhg Furlong based on today's evidence.
Eoin Reddan and Madigan are the reserve half backs, leaving one place to fill on the bench as back line cover. Darren Cave put in another good performance at centre but his lack of versatility will count against him as Fitzgerald and Zebo (assuming Earls, R. Kearney and Bowe are starters) look to be the front-runners for that final spot, meaning there's no space for Dave Kearney or Paddy Jackson.
What a wonderful headache to have.
