Sean Cronin and Mick Kearney say Ireland must be wary of the wounded animal when they host England in the final round of the Guinness Six Nations championship, but believe the visitors have too many issues to address before they can deny Andy Farrell's side the Grand Slam.Ireland are just one win away from would would be just their fourth Grand Slam title, and first on Irish soil since 1948, with England their final opposition on Saturday evening at 5pm.Andy Farrell's side come into the game in flying form, comfortably seeing past Scotland to make it four wins from four last week, while it was a contrasting weekend for England, who suffered their heaviest Twickenhem defeat, beaten 53-10 by France.Six years ago, the roles were reversed, with Ireland ending an otherwise disappointing campaign by beating England 13-9 in the final game of the championship, denying Eddie Jones' side a Grand Slam.And Cronin says there's a real motivation to be found in ruining the opposition's party."I would have an element of fear," he told the RTÉ Rugby podcast."They're playing for pride this week, they're wounded, they'll get a couple of players back who historically have caused us issues, like Tuilagi."Cronin was joined on the podcast by his former Leinster teammate Mick Kearney, who believes that while we will see a much-improved England this week, they won't have enough to ruin the Aviva Stadium party."England have so many different motivations this week," Kearney said."They were hockeyed by France last week which brought a huge amount of delight to many nations, I can imagine."Coming to Ireland, they've nothing to lose.
