Jonathan Davies is set to face a player he describes as Ireland’s “general” when Wales enter win-or-bust RBS 6 Nations territory on Saturday.
Davies might be opposing Ireland's fly-half talisman Johnny Sexton at the Millennium Stadium, but he also has first-hand experience of playing alongside him.
Wales centre Davies and Sexton started all three Tests for the 2013 British and Irish Lions against Australia, and the Clermont Auvergne star knows what to expect from Ireland’s celebrated number 10.
“He is obviously their general and marshals their troops,” Davies said.
“I noticed that in Australia. He expected high standards at training.
“He knew his role and expected everyone else to know them. If you didn’t, he gave you an earful.
“That’s what professional rugby is about. He is one of the best in the world at the moment at marshalling the game.”
Sexton, who is currently battling a hamstring strain, is pivotal to Irish hopes of retaining the Six Nations title and securing a possible Grand Slam.
Victory against Wales would leave Ireland one more win away from guaranteeing both objectives, but Davies and company will be removed from the title equation if they do not topple an Irish team unbeaten against them in Six Nations combat since 2012.
“Ireland are (ranked) third in the world and they have won 10 games in a row,” Davies added.
“They are a very good team, they are defending (Six Nations) champions and are well-coached.
“It’s a tough task for us, and we have to make sure we get a good week’s preparation and really focus on the game.”
Wales head coach Warren Gatland is due to name his team on Tuesday, with Davies and midfield partner Jamie Roberts set to feature in what will probably be an unchanged line-up following victory over France nine days ago.
Gatland, meanwhile, has added fit-again Scarlets hooker Ken Owens to the Six Nations squad, with Owens reporting for training on Monday.
Davies and Roberts became accustomed to opposing an ultra-experienced Irish centre combination of Brian O’Driscoll and Gordon D’Arcy during their Test careers, but this time around it will be a new unit of Jared Payne and Robbie Henshaw facing them.
“Their centre partnership is a good one,” Davies said. “They are big boots to fill, and they seem to be doing quite well.
“They have played well together and seem to have a good understanding, which is important for a centre pairing.
“They understand their roles and what each other is doing. That normally takes a bit of time, but they seem to have taken to it really quickly.
“There is always pressure on anyone with the Welsh jersey on to perform. We put that on ourselves, to make sure that we deliver a performance worthy of the jersey and make sure we get the victory.”
