Centre Jonathan Davies has said that Wales must target Jonathan Sexton during their Six Nations match against Ireland on Saturday.
Davies played with Sexton on the 2013 British and Irish Lions tour of Australia and thinks that the player will be difficult to deal with.
"He is obviously their general and marshals their troops," Davies told Sky Sports News.
"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.
"Ireland are third in the world and they have won 10 games in a row. They are a very good team, they are defending champions and are well-coached."
Wales can move level on points with Ireland with a win on Saturday.
