Brighton & Hove Albion defender Shane Duffy is confident that the Republic of Ireland can qualify for the 2018 FIFA World Cup in Russia.

Ireland managed a 0-0 draw against Denmark away from home in the first leg of their World Cup qualification playoffs on Saturday and ahead of the return fixture on Tuesday, Duffy is confident that his side can get the job done at the Aviva Stadium in front of their fans.

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."
