LA Galaxy striker has stated that he will change his style of play if the manager decides to change the traditional system of 4-4-2
"We have kind of done the same system since the manager took over," Keane told RTE. "So the players are certainly used to that."
He continued: "But if there was an adjustment, it would be little minor things, I think.
"As players, you are always set different roles when you go out on to the pitch. Myself, for example, to just sit on the holding midfielder and don't let him dictate the game too much. It would be little, small things like that.
"I wouldn't say it would be formation changes. We wouldn't automatically just go to 4-3-3 when we haven't done it for a long time."
The LA Galaxy striker states that he has experience playing as a link between the midfield and attack at club level, where he says he played as a 'number 10'.
"It's something I have done," he said. "I have kind of played two different roles, if you like, at club level and international level.
He added: "At international level, the pressure is on me to score the goals, but at club level, I kind of play as that number 10 anyway.
"Maybe if the manager wants me to do that role, which I am sure in certain games he will probably want that, it's something I have done before, so it wouldn't be a problem."
And the Dubliner believes that the squad is itching to get the tournament underway after the extended preparation which began in Dublin some weeks ago.
"We are desperate to get started now," said Keane.
"It's been a long few weeks. It's been very good. The atmosphere around the place has been brilliant. Everybody is just looking forward to Sunday now."
The former Tottenham and Liverpool man also told the media that Ireland were not going to Poland to make up the numbers and would be playing to win.
He said: "In any competition, you want to start off straight away as well as you can and try to get points on the board because we know that in the group, anybody can beat anybody.
"We knew from Monday onwards that we are getting to the end of things now. It was good training today with the lads and we will look forward to the next couple of days and preparing for Sunday's game."
He added: "Listen, we are not coming to this competition to make the numbers up. We are here to do as well as we can for the country and hopefully go as far as we can.
"We go into every game in every competition believing that we can win it," concluded Keane.
