SHANE DUFFY believes the Irish can complete their World Cup job – after a FOURTH successive away clean sheet for club and country.

Duffy helped the Republic of Ireland to a 0-0 draw away to Denmark in the first leg of their World Cup qualification play-off.

Irish boss Martin O’Neill has warned his team might have to score twice to go through.

But Duffy is eyeing another shut-out.

He said: “We are quite satisfied we kept a clean sheet against a good nation.

“If you had told me at the start of the campaign we’d have to beat Denmark in Dublin to go the World Cup, I’d have taken it. If we can keep them out on their home patch we can do it on our home patch.

“They are a good team, a very good team and it was a very tough night but you could see their technical players struggled.

“It was a great performance defensively from the whole team. They will probably fancy their chances of scoring a goal in Dublin but we’ll be a different team at the Aviva.

“We don’t concede many goals and hopefully we don’t concede on Tuesday but we can be a bit better on the ball and we will create a lot more.”

Duffy played for the Irish at Euro 2016 and would love to add a World Cup.

He said: “It’s a cup final on Tuesday now. One game, one win and we’re at the World Cup so let’s go for it.”

Duffy has not been involved in conceding an away goal since seeing Alex Iwobi score Arsenal’s second against Albion on October 1.

Since then he has helped his club to away clean sheets at West Ham and Swansea.

And he has played for the Irish in shut-outs away to Wales and the Danes.

The next challenge to that unbeatable run comes when Albion play Manchester United at Old Trafford.
