It’s pretty straight-forward for Northern Ireland when it comes to goals - David Healy must score. The Sunderland forward has never been a true hotshot at club level, but he has a record recorded 34 goals for his country and finished as top scorer in qualifying for Euro 2008 with 13 strikes. Nigel Worthington’s team also features experience in the shape of veteran winger Keith Gillespie, but will be without injured trio Sammy Clingan (shoulder), Stephen Craigan (hip) and Michael Duff (ribs) who have all pulled out of the squad. Slovenia will fancy their chances on home soil, after making an undefeated start. Cologne striker Milivoje Novakovic is their danger man after netting twice in the last game, a 2-1 win over Slovakia.
