With France on the horizon, Ireland don't exactly have time to wallow in the pain of a bitterly disappointing defeat to Wales but Simon Easterby admits that regret will linger.

'Gaining momentum' is the most common pre-Six Nations soundbite but a 21-16 opening-round loss in Cardiff, and more so the manner of the defeat, means that Andy Farrell's championship hopes depend on beating Les Bleus in Dublin on Sunday. 

Ireland played for 66 minutes with 14 players following Peter O’Mahony’s red card and then blew a 13-6 lead with the concession of two second-half tries, both of which could easily have been avoided. 

In addition, Billy Burns missed a late penalty kick for touch that cost Ireland a chance to draw or even win the match. 

"This group is really resilient and I don't believe it’s that hard to [lift them]," Easterby told RTÉ Sport. 

"Disappointment will live with the lads for a good while, I’m sure. 

"But we know in sport you get an opportunity to turn things around and play quickly after a defeat, there’s no better thing to do. 

"We’ve had a day of recovery, mental and physical yesterday, chats around the group, the opportunity for players to air a few thoughts and for them to chat among themselves and as coaches for us to reflect on the performance and today it’s back to business.

"We have to hit the ground running and as much as there’s a few sore bodies around, mentally the players are in a good place and they understand what it will take to get a result this weekend and the need to do that to stay alive in the competition." 

The infamous Monday morning video sessions under former head coach Joe Schmidt may be a thing of the past but that's not to say there's not a great deal of introspection as the match and mistakes are reviewed. 

Asked about the new approach as the squad revisit the weekend, Easterby (above right) said: "I guess we believe in what Faz [Andy Farrell] has created here is an opportunity for players to have an opinion. 

"When we as coaches are sitting and reflecting on a game, we're not in it, we are not the ones making those decisions and making the calls so it’s about a collaboration, I guess, of thoughts and understanding. 

"What parts of the game we think we could do better, parts of the game we thought we did well and parts of the game that we need to improve on. 

"Looking at ourselves first and foremost. Then we’ll be starting to cast an eye today and the course of the week to what’s coming up next weekend. 

"Certainly, it’s an opportunity for everyone to open up and have an opinion about the performance, whether they started, whether they were on the bench or whether they are in the wider squad." 

France, who finished in second place last season on points difference, beat Italy 50-10 in Rome at the weekend and have their sights firmly set on victory in Dublin, a feat not achieved since 2011. 

"They pose threats across the park. You saw at the weekend how dangerous they can be if you offer them the space," said Easterby of their seven-try runaway victory.

"It's certainly something that we are fully aware of. What we need to do is make sure that we can be better at what we do, whoever we’re playing against. 

"We conceded two tries at the weekend and I think both were avoidable, regardless of whether we were 14 or 15 men on the pitch. 

"The threats that they will pose are greater than some teams, no doubt. 

"Ball in hand, their ability to attack the gainline, to offload, to get behind teams, their kicking game. 

"They are a multi-threat team but if we get our own house in order it becomes a lot easier to defend any team, regardless of their individuals."
