Robbie Keane has admitted the Republic of Ireland have never had a Plan B throughout his entire international career.
The 33-year-old striker is in line to win his 129th cap in Austria on Tuesday evening with Ireland's hopes of World Cup qualification having taken a severe hit with Friday's 2-1 home defeat by Sweden.
Giovanni Trapattoni's seemingly inflexible tactics have provoked increasing criticism, but Keane insists the national team have always had just one way of playing.
He said: "We talk about Plan A and Plan B and stuff like that, but Ireland has never had a Plan B before. We have always had Plan A, it's as simple as that.
"Since I have been in the squad, we have played the exact same way. We don't have the personnel to, like Spain, get the ball down and have 80 per cent possession against teams. We are just not that team.
"But we know strengths and we stick to them. Unless it changes, maybe from grass-roots - but it's not going to change for, certainly, a good few years.
"They keep talking in England about trying to change things and making the national team a lot better. In Ireland, we need to do that as well, but is it going to change straight away?
"It hasn't changed since I walked in that door the first day I got here, so I don't think it's going to change for a while."
Keane has not given up hope of snatching a play-off berth with victory at the Ernst Happel stadium, but accepts that qualification will be a tough task.
He said: "We have got a great opportunity tomorrow to get three points and then you never know what can happen.
"Is it going to be tough? Of course it is. We are not naive enough to think it's going to be easy to qualify now.
"It's going to be tough, but we still have to believe that we have got a chance to do that."
