Ireland scrum-half Conor Murray said his side will have to watch opposite number Danny Care closely during their Six Nations clash with England.
Joe Schmidt's side enter the game knowing that victory would see them claim the Triple Crown, with the battle of the nines key at Twickenham.
Ireland have beaten Scotland and Wales without conceding a try, but Murray believes Care will be a different threat to monitor if they are to triumph.
"He's as dangerous as any in the world with the ball in hand," the 24-year-old told Sky Sports.
"I played against him last year and in the Heineken as well, and leading into that game we had a good look at him.
"He's a threat from anywhere, he'll try anything from anywhere and he has the ability to pull off some really spectacular plays.
"So he's definitely a player we'll have to keep an eye on. Quick taps, little snipes, he's going to go from everywhere.
"Whoever's in the line of defence, whoever's closest to the ruck will have to watch him closely; he likes to snipe in and around there.
"He'll try little dinks, he'll throw offloads, and whoever's in that front line has got to be switched on.
"I'll obviously hope to be in behind that looking for those little chips, but whoever's up in the front line I'll just be talking to them, making sure we keep an eye on him at all times."
