Republic of Ireland need near 'perfect' game to beat Portugal - Hallgrimsson

Heimir Hallgrimsson has admitted the Republic of Ireland will have to produce a near “perfect” display if they are to get a positive result in Saturday night’s World Cup qualifier against Portugal.Ireland head into the game at the Jose Alvalade Stadium with their Group F hopes already severely damaged by last month’s home draw with Hungary and humbling 2-1 defeat in Armenia.They will have to produce something special in Lisbon if they are to give themselves something upon which to build when the Armenians head for Dublin next Tuesday, and their head coach knows the margin for error is almost non-existent.
