Ireland head coach Andy Farrell has warned his side to guard against desperation as they face England in the final round of the Six Nations competition in Dublin on Saturday.
Farrell's men are the only team to have a chance of winning the Grand Slam having recorded four wins from as many games in the competition and now will be facing England, who were hammered by France with a 10-53 defeat at Twickenham Stadium.
They also are the number one ranked side in the World Rugby Rankings having defeated the All Blacks in New Zealand during the summer last year but despite their consistency, Farrell wants them to remain balanced.
"Getting the balance right,” he said.
"To me, desperation is an illness. You want to stay away from that.
"You can't be accurate if you're desperate; being calm enough to be yourself, being controlled enough to be accurate when it matters is a temperament that we're all chasing."
Meanwhile, Caelan Doris and Dan Sheehan have been declared fit for Ireland while Robbie Henshaw and Ryan Baird replace Garry Ringrose and Iain Henderson. Also Jamison Gibson-Park takes over from Conor Murray at scrum half.
Ireland: Keenan; Hansen, Henshaw, Aki, Lowe; Sexton (capt), Gibson-Park; Porter, Sheehan, Furlong; Baird, Ryan; O'Mahony, van der Flier, Doris.
Reserves: Herring, Healy, O'Toole, Treadwell, Conan, Murray, R Byrne, O'Brien.
