"And I will be really confident that that will be demonstrated".
The absence of O'Connell at lineouts will be missed but former Ireland worldwide Shane Horgan is backing Devin Toner and Iain Henderson to stand up and be counted. Mike Ross, 4. Iain Henderson, 5. He's getting around and everybody's helping him out.
A semi-final spot at the Rugby World Cup is up for grabs when Ireland face-off against Argentina on Sunday.
Thankfully for Schmidt, he was able to name Sexton at fly-half in a backline missing influential centre Jared Payne (foot fracture) after the fly-half recovered from a groin injury suffered against France.
First entered a Kilkenny man who lives in Singapore and was on his way to Switzerland, but meeting his family in Cardiff before they supported Ireland in their clash with Argentina tomorrow. If he's fit he's fit.
"We don't take too many risks with injured players and we have got a great medical group and Johnny is ready to go". But there are always risks in everything you do. It's been a very light training week, we've got a few guys carrying bumps and bruises. "But I think we should focus more on our game and the change in our style that has been working so far".
Madigan came on in place for Sexton in last week's 24-9 win over France and his performance has made him Joe Schmidt's obvious choice to replace the 30-year-old.
This could be Ireland's last week at what has been a wonderful World Cup.
It was against Ireland in Lens, in 1999, that Argentina announced themselves as a world power and went on to confirm it eight years later, ending Ireland's lacklustre campaign in the pool stages, while going on to reach the semi-final, something their opponents have yet to manage.
Argentinian fly-half Felipe Contepomi - on media duties at this World Cup - developed a personal rivalry with Ronan O'Gara when he joined Leinster in 2006, and he spoke publicly of his hatred for Munster, with O'Gara often in the firing line.
"The team has improved a lot since we joined the Rugby Championship", said Landajo.
Five times Ireland have played in the quarterfinals and five times they have lost.
Argentina's unorthodox "Bajada" scrummaging method has caught several sides cold in the World Cup, the locks unusually binding on the props hips in a bid to pin all the pressure through the opposing hooker.
"It's just making sure we get to that point that we can do it".
Clive Woodward was required to fight tooth and nail for the time he needed with his players, and the schism between the clubs, who pay the players, and the English RFU, who essentially borrow them, has never been closed.
"They're very similar, yet very different". He wanted to go with Simon Easterby on the blindside and myself on the openside to try and upset the Argentinians and be physical with them.
"It's a big weapon for them". And by "injury" they meane it came off the bone.
"Obviously it's important", Pumas centre Juan Martin Hernandez said of the Irish absentees.
The Puma hope the World Cup is not finished for Bosch, and that means winning at Millennium Stadium in Cardiff on Sunday. That's three key forwards out of contention in a matter of days. For 40 minutes the pack arm-wrestled its way to a slim half-time lead and then the backs had their say, running in five tries to make seven in all.
"Football in Argentina is like that - we have the best players in Messi and Maradona - but four years ago Argentina didn't play rugby like that".
