The 32 year-old is currently enjoying his football in the US with LA Galaxy.
Keane admitted he had started to look at the prospect of management when he is forced to retire.
He said: "Of course. It's the only thing I know. When I stop playing football, what else am I going to do? This is all I know.
"I wake up every morning and look forward to going training. I could never imagine the day that's going to end, so it's certainly something I am going to look into.
"I am doing my coaching badges in December - but I am going to try to play as long as I can first."
