Republic of Ireland manager Martin O'Neill has stressed that decisions will ultimately be made by him as he nears his first game in charge of the Boys in Green.
The former Celtic and Aston Villa boss said that he had "great respect" for Keane and likened the former Manchester United captain to his long-time assistant manager John Robertson, but insisted that he would not be over-ruled by the Cork native.
"I don't really want to change Roy Keane," O'Neill told reporters. "I don't think that was the intention, otherwise it loses its impetus.
"Of course there are things we want to adjust and look at, but I have had an assistant manager in John Robertson for years and years at all the clubs I have been involved in, or most of them, and John was very, very good."
He continued: "John was more than a sounding board, more than that. I listened to his opinion, he had a very good opinion about football, he was a good judge of a player as well.
"But ultimately, he always left the decisions to me and that was the main thing. That's something that I have been used to now for 20 years and I wouldn't be expecting anybody to be over-ruling me.
"That's not the big 'I am', far from it. I have got great respect for Roy Keane, otherwise I wouldn't have asked him to do the job," added the 61-year-old.
O'Neill will take to the dug-out as Ireland boss for the first time on November 15 against Latvia before taking on Polan four days later.
