Ronan O’Gara thinks that Ireland’s mental strength, gained from wins over Scotland and Wales, will be a major cause of concern for England.

The sides meet in Twickenham on Saturday week in the third round of the Six Nations and former Munster and Ireland out-half O’Gara reckons the visitors will have the edge if the match is close.

Asked what will concern Stuart Lancaster’s side the most, O’Gara told RTÉ Sport: “I hope they are worried about the Irish mentality. There’s a team of winners there.

“There’s massive self-belief there. I think if it goes to the wire I’d back the resolve of the Irish, that’s what I hope they are worried about ‘cos there are some fantastic players, fantastic people on the pitch."

The Racing Metro coach added: “I just think that when it comes down to a one-score game after 72 minutes, the Irish boys know how to get over the line and that’s what they’ll be fearful of because the English players haven’t done that at any level. That’s what should give the Irish boys confidence.”
