Conor Murray has claimed that keeping England scrum-half Danny Care quiet could be the key to an Irish victory at Twickenham on Saturday.
Ireland's scrum-half believes that his opposite number may be the main threat to Ireland's chances of continuing their unbeaten run in the Six Nations this year.
"He's as dangerous as any in the world with the ball in hand," Murray told reporters.
"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."
Ireland have not yet conceded a try in this year's tournament.
