Ireland and Serbia lead the way in Group D
Ireland international Robbie Brady is staying focused on Austria as talk of World Cup qualification intensifies.
Martin O'Neill's side are unbeaten in five matches thus far and lead the way in Group D alongside Serbia on 11 points.
Wales and Austria are four points behind on seven at the half-way point in the qualifying campaign.
However, Brady isn't taking anything for granted ahead of Sunday's crucial match against Austria.
"We always expect to have tough groups," said the Burnley midfielder, adding: "We've always had tough groups, over the time I've been in anyway.
"But these groups are strange like I said. One result could change everything so you need to stay focused."
Ireland welcome Austria to Aviva Stadium on Sunday knowing a win puts them in a commanding position in the group before Wales and Serbia face-off later.
