"I'm not walking out today - we've got a game tomorrow," Keane told his pre-match briefing at Sunderland's Wearside academy today.
"I am very much focused on the job. I came here for three years and I would like to think that I can see that out at least.
"That's' what I am focused on. We have made good progress which I keep saying week-in, week-out."
Keane also played down his assertion that he would not tolerate abuse from fans.
"Sometimes I like to stir things up to see if I can get a reaction," the 37-year-old said. "I was not happy with what I saw the other night and I said that both with one or two supporters and the players. Today is a new day and we have a big challenge against Aston Villa tomorrow.
"I stand by what I said. There are one or two people who have come down to the dug-out. This has happened before and I don't think it should be tolerated.
"It's not like we haven't won in 10 games and it's not right.
"My opinions on that haven't changed and I know a lot has been made of what I said but that doesn't particularly bother me - that's the way I am.
"I know more experienced managers than me tend to choose their words very carefully and generally so do I. But I try to say it as I see it and that will never change.
"I never came into sports to be popular or to be liked. I came into football because I love the game first and foremost and I like to win. If I upset people along the way that's tough.
"But trust me a lot of people upset me. It's part of the challenge. It's part of the bigger picture and I appreciate you will have disappointments. I remember defeats like they were yesterday.
"In the Championship we had set-backs and last year we did also, but in terms of the overall plans, shall we say we are very much on course to achieve what we set out.
"No doubt you are gong to have set-backs along the way. Considering we have setbacks in the last week or two we have still managed to get through the next round of the Carling Cup when we were down to ten men for the last half-hour and were two goals down with four minutes to go.
