The former Liverpool striker quickly fell out of favour when Capello took over as national team boss in 2008, with injuries also undermining his chances of a recall. But 31-year-old Owen - who has 89 caps and 40 goals - still shows his class when opportunities arise and scored in United's midweek Carling Cup win at Leeds.
And he admits he would seize his chance should Capello change his mind.
Owen told the Observer: "I was in every squad for over a decade and all of a sudden it stopped one day.
"I would never turn my back on it, but obviously there's a scar there that still hurts a bit. But I don't get upset now when I'm not in the squad, like I used to.
"If I got a call-up I'd be there within five minutes.
"Fabio Capello picked his first squad and I was on the bench. I thought: 'This might be a sign that he doesn't fancy me.' The next time I wasn't in the squad, and that's just been that."
