Ireland 'won't be worrying about who's favourites'
France are trying to ease the World Cup pressure by branding Ireland favourites for next weekend's Pool D decider, according to Sean O'Brien.
Flanker O'Brien labelled French claims Ireland are odds-on to win in Cardiff on Sunday as "kidology", after Joe Schmidt's men reached the quarter-finals with a 16-9 victory over Italy.
Leinster wrecking-ball O'Brien admitted Ireland are already steeling themselves for a brutal encounter with the French, that they fully expect to be spearheaded by freight-train centre Mathieu Bastareaud.
"They all say that? I wouldn't buy into that," said O'Brien when told France have installed Ireland as favourites.
"Of course they want to say that, it's a bit of kidology.
"But we won't be looking into whether we're favourites or not.
"We'll have to prepare ourselves and make sure we're ready to go on the day.
"And we won't be worrying about who's favourites or otherwise.
"We've lost a lot of games against them in previous encounters.
"This is different, it's a World Cup, a new season, so it's all to play for and that changes everything."
France have failed to beat Ireland in the their last four meetings, with Joe Schmidt's men claiming two victories en route to consecutive Six Nations triumphs.
Toulon powerhouse centre Bastareaud has proved a constant scourge for Ireland's backline in recent times, and O'Brien accepted they must stand firm against the 27-year-old once again.
"France are very physical, they pride themselves on that and it will be no different when they play us," said O'Brien.
"We have to expect huge physicality, at international level you're going to be in for a battle.
"So you've got to prepare yourself for that in the week and make sure you're ready to rock at the weekend.
"Bastareuad is always someone who will lead that charge for them.
"You've got to take his space away, he's an intelligent rugby player, he's obviously very, very strong and he's a leader for France.
"He's a very, very dangerous player and one we've got to keep an eye out for."
Beat France and Ireland can expect a quarter-final against Argentina, lose and they will face the All Blacks.
