London Irish lock Bob Casey is backing Ireland to scupper England's charge towards the Grand Slam on Saturday.
England will travel to Dublin with four wins under their belts in this season's RBS Six Nations - while Ireland have suffered defeats to France and Wales.
However Ireland have won six of their past seven games against England - and Casey is confident they can upset the odds again.
"It's fantastically poised with England going for the Grand Slam, so it should be a cracker," said the 32-year-old.
"I really feel that Ireland can turn England over having gone very well against them over the last five or six seasons, at home especially. With the experience we have I think we can do it."
Ireland were left smarting by their 19-13 defeat to Wales last time out - with the game ultimately being settled by a controversial try from Mike Phillips.
The Wales scrum-half had taken the ball from Matthew Rees' quick lineout out to score in the corner - however the try should not have been allowed as the wrong ball had been used.
And Casey, who has been capped seven times, believes it is vital for the Irish to put this result behind them.
"It's been a strange one for Ireland because I don't think we've necessarily played badly it's just that results have not been going our way," he said.
"It's now important for the boys to push on after the disappointment of last weekend against Wales and that starts with this weekend against England. "
