The 30-year-old has failed to become a regular since joining United on a free transfer from Newcastle last summer.
“You can only do your best and prepare and train well, so that you are ready when the manager calls on you,” said Owen.
“After that, it’s up to the manager who he chooses.
“It sounds easy, but probably the most difficult thing is not playing for a couple of weeks and then all of a sudden getting called up and being mentally and physically right to perform well.
“At the end of the season, I’ll look and think, ‘Was I happy with the amount of games I was available for?’, ‘Did I score enough goals in the games when I played?’ and ‘Did I play well enough in those games?’
“You look at highlights of the season, did we win anything, things like that. But I wouldn’t put any goal or appearance totals out there because, at a club like this, you never know when the manager is going to use you.”
