The Sunderland defender is optimistic that the Boys in Green can get a good result in Astana against Kazakhstan to kick start the World Cup qualification campaign
The Boys in Green face Kazakhstan in Astana on Friday September 7 and the former Manchester United defender believes that it is important for the team to get a good result in order to put their Euro 2012 woes behind them.
"We need to give everyone a bit of a lift and forget about the Euros," O'Shea told the Irish Independent. "We want to get the feel-good factor back again and it would help if we can get a win in our first qualifying game.
He continued: "We've been watching a few videos and they're quite a fast counter-attacking team and we'll have to be prepared. The smaller countries are improving their tactics a lot and their set-pieces. If we are not fully concentrated, they can catch you out."
"But if we're not up to our usual standards for a qualifying game, we'll get caught out because the pitch (artificial surface) is going to be an unknown and we'll only train on it the night before. If we are professional and our usual selves, I can see us getting the win."
Giovanni Trapattoni's men are expected to battle with Sweden for second place in the group, with Germany being the favourites to progress automatically, but O'Shea said that Ireland can 'cause Germany problems'.
"I spoke to (Sunderland team mate) Seb Larsson and they are thinking along the same lines," said O'Shea. "Everyone seems to be counting Germany for first spot and then it's the battle for second.
"But if you go into it like that... we can cause Germany problems but let's be honest and realistic about it, Germany have a fantastic squad with unbelievable young players and experience too.
"It will be tough to top the group but we are more than capable of coming second," concluded the defender.
