The Irish need to win if they are to stay in control of their Euro 2012 playoff fortunes, and the former Tottenham man says a poor pitch should not distract his team-mates
However, when asked about the last time he played on a such a bad pitch, the former Tottenham Hotspur favourite told reporters that his side cannot have any excuses for a poor performance.
He said: "It was probably a reserve game when I was at Wolves, maybe.
"But we can't be worrying too much about the pitch or the stadium because when we were younger, a lot of us played on pitches like this.
"Of course, over the years we have been spoiled playing in great stadiums and on great pitches, but it's the same for both teams, so we can't have any excuses.
"We have to stop that now. After the game, whatever happens, we will have no excuses.
"We are looking forward to the game. Of course it is different circumstances to what we are used to, but just have to get on with it."
Ireland need six points from their remaining two games to guarantee them a play-off spot, and despite being clear favourites, Keane insists that his side must remain focused.
"You go into every game wanting to win. We are the clear favourites and rightly so, but we have to just concentrate on what we are doing and focus on our own jobs,” he said.
"We can't just come here and think we are just going to get three points and that's it, and walk out.
"We have to earn it and give 100 per cent, and we will do that."
The 31-year-old striker, who recently made the move to MLS side Los Angeles Galaxy, also reassured fans that the thousands of miles he must travel to meet up with the rest of the squad has had no bearing on his preparation for matches.
He continued: "I have been sleeping the same as I would. The last week has been fine, sleeping as normal, so I have no complaints there at all.
"As soon as I leave, I switch the clock and I have been lucky enough that I've slept really well and it's been fine."
