Owen, 31, has not featured for the Three Lions since playing in a friendly against France in March 2008.
He told The Guardian: "I was disappointed for the first squad I missed, a little bit less for the next one and after about three or four times, I didn't really expect to see my name.
"For the first couple of squads I looked at the players [named] and looked at what I had done. For the last dozen squads, I haven't looked. I don't even think about [being picked] now. Honestly.
"It's sad, really. If I keep getting up for something, then [find out] I am not in, I am just kidding myself."
