The Sunderland centre back has expressed the belief that the Boys in Green must focus on defeating other teams in the group, as they search for a play-off spot
The Boys in Green face the Faroe Islands on Tuesday after the heavy home loss to Die Mannschaft and O'Shea believes that Ireland must aim for a play-off place.
"The games that decide qualification won’t be the Germany matches," he told reporters. "They are going to be Austria and Sweden although that’s not forgetting about Kazakhstan or the Faroe Islands either."
He continued: "The Faroes have proven to be very difficult opponents already for other teams in the group but we have to be aiming to at least finish in the play-off place. If you want to do that then you have to be beating these teams.
"Thankfully this game has come around really quickly and we can get three qualifying points towards qualifying for the World Cup."
After witnessing the heavy loss to Germany - Ireland's worst ever competitive home defeat - a section of the Irish support booed the team off the pitch and O'Shea said that they were within their rights to do so.
"I would say that they were exactly right to do it. I’m surprised the whole stadium did not do it after a 6-1 loss," said the Sunderland defender.
"When you come to watch a team to try to get a win and it loses 6-1, it’s not the result that you want and you are not going to be happy.
"We will see how the players respond tomorrow. We have to put a performance in to get ourselves back in with a chance of qualifying from the group," he concluded.
