Martin O'Neill admits Ireland may need two goals to qualify

Martin O'Neill has warned the Republic of Ireland they may have to score twice to beat Denmark to a place at the World Cup finals in Russia.

O'Neill's men emerged from their play-off first leg trip to Copenhagen with a hard-fought 0-0 draw, but the 65-year-old was quick to admit that keeping Christian Eriksen and company quiet all over again in Dublin on Tuesday night may prove difficult.
