Ireland coach Eddie O’Sullivan has braced his players for a ferocious onslaught from England tomorrow with the stricken world champions seeking to "exorcise their demons".

Andy Robinson’s side are desperate to restore a reputation battered by successive humiliating defeats by Scotland and France in what has become another dismal Six Nations campaign.

The 31-6 thumping in Paris last Sunday marked the lowest point of Robinson’s rein and the head coach reacted by axing six World Cup winners.

Another defeat would crank up the pressure on England’s coaching team to fresh levels with Robinson and his lieutenants Phil Larder and Joe Lydon in the firing line.

With so much at stake, O’Sullivan expects the Irish line to be exposed to a fearful early battering and has warned his Triple Crown hopefuls to discard thoughts England are vulnerable.

"England are under pressure and they do need a performance tomorrow. They have a lot to prove. They’ll be very disappointed with their championship overall," he said.

"Last week’s display in Paris was well below par. If they come out and hit the ground running they’ll exorcise their demons.

"They’ll want to bounce back and are a very powerful side. There will be a very physical element to their game tomorrow - they’ll come at us early on and see if we’re up for the task or not.

"If England click, they can have a really big day out. At Twickenham they are more likely to click than not click. They ran the All Blacks very close last autumn.

"If they reproduce that display they’ll be thinking they can see off Ireland. Maybe they won’t click tomorrow because they’ve made a lot of changes.

"It’s hard to know, but England tend not to put bad back-to-back performances together.

"A mantra of Sir Clive Woodward’s was the test of a good team lies in how they respond to adversity. That will be what they’ve talked about.

"The platform has been set up for them to erase a bad performance with a good one. England aren’t vulnerable all of a sudden - they’ll be more galvanised."
