Shane Duffy and the Republic of Ireland have been told they still have a lot to do if they are to get to the World Cup finals.

The Albion centre-back shared in a fourth successive away clean sheet for club and country as the Republic drew 0-0 in Denmark in the first leg of their qualification play-off.

Irish boss Martin O'Neill would love another shut-out in the return fixture in Dublin on Tuesday.

But he accepts his side might need to score twice against the dangerous Danes.

O'Neill said: "With the players that they possess, I believe that they are capable of scoring a goal, so it means we might have to score two to win the match.

"That's the way I am looking at it, and we will have to show a bit more creativity during the course of the game at the Aviva. But I think we are capable of doing that.

"Urged on by a big crowd as well, we have a lot to play for."
