The Sunderland defender will skipper the Boys in Green against Austria and he believes that they can get a result if they concentrate on their own game
Ireland welcome Marcel Koller's side to the Aviva Stadium on Tuesday, March 26, in Group C of the World Cup qualifiers and O'Shea is wary of the threat that is posed by Das Team.
"Austria will be thinking they're kind of the forgotten team behind Ireland and Sweden for the second place but they're a very good outfit with experienced players and some good young lads as well," O'Shea told reporters.
"We'll be going through the video so we'll have our homework done and, fingers crossed, we can get about Austria like we did Sweden in terms of the pressing game and the shutting down. The team was very good as a cohesive unit the other night and we need to take that forward into Tuesday." added the 31-year-old.
However, while noting the Austrian threat, O'Shea believes that Ireland must concentrate on their own game and ensure that they are 'more clinical' on Tuesday evening.
He said: "It will be interesting to see the Austrians' approach. Will they sit back or have a go at us? I think that will dictate but we just have to worry about ourselves initially, hopefully get the crowd going.
"If we are focused and concentrated like we were the other night we should be okay. But we will have to be a bit more clinical. Our final pass the other night [let us down]."
Meanwhile, David Forde has expressed his delight at becoming Ireland's number one goalkeeper.
"It's massive, you know, when somebody like Trapattoni turns around and says that you're the country’s number one," Forde told reporters. "It's a massive shot in the arm when it's someone of the manager's calibre. It's big for me. I'm delighted to play for my country, it's something I always wanted to do. I'm just delighted."
The 33-year-old Millwall shot-stopper became the oldest player ever to make a competitive debut for Ireland when he featured against Sweden on March 22 and is hopeful that the squad can build upon the positive result in Stockholm.
He said: "The result in Sweden certainly gives us confidence. It was a clean sheet away from home and we had the chances and opportunities, so, yes, it's given us a good chance.
"We know what we have to do now and hopefully we can get a big home crowd and make it very intimidating for Austria. It’s going to be a tough game, but we want to make it as tough as possible for them. There's a lot riding on it"
