Ambitious Championship outfit Brighton expressed an interest in January and there are bound to be plenty of suitors despite Owen's patchy fitness record.
And he has not completely given up on United.
"I know what I want to do," he said. "If you say certain things they can get misconstrued but I have not lost the passion to be playing more often.
"In life, you have to make hard decisions. I have made some good ones and some bad, but in general terms I am pretty proud of my career.
"I still think I have another two or three years but where that will be is a question that the manager would be better placed to answer.
"I am exactly the same situation I was last year."
