The Champions League winner comes off contract at the end of this season.
Milner remains locked in talks with the Reds over a new deal but the two parties are yet to reach an agreement - with the 33-year-old stating his desire to stay on Merseyside for at least another campaign.
And on former club Leeds, Milner told The Sportsman: "I'm a fan. I always follow the team and the results. So you can never say no or even yes because just so much changes in football, you never know what happens.
"At the moment I'm a Champions League winner with Liverpool and this year we're really going for the Premier League, but I don't know what the future will hold.
"It would be amazing to play for Leeds again but no one from the club has ever contacted me about that.
"People talk about my age and that I'm getting on, and could I continue after Liverpool, but I don't think I'm typical physically for my age."
