The 33-year-old, who was released by Manchester United last summer after three injury-ravaged years, has failed to make the impact he wanted since joining Stoke last September. That has again mostly been down to fitness problems but Owen admits there have been "other reasons" for his lack of action.
Speaking in 'Potters', Stoke's official matchday programme, Owen said: "It hasn't quite worked out as planned for whatever reason and part of that is due to having a couple of niggling injuries, but other parts of it are down to other reasons."
He added: "The season hasn't gone the way I wanted it to because I have hardly played, hardly scored and haven't really been involved in the season at all as yet.
"Hopefully though, the second half of the season can be a lot better for me."
Owen, who made his name as a precocious teenager with Liverpool, notched his first goal for Stoke - his 150th in the Premier League - in last week's defeat at Swansea.
He said: "It's obviously nice to do it, but I must admit I did fear that I would never get there, to be honest with you.
"With the lack of action I have had and one or two niggling injuries I have picked up, you do worry and think that it just isn't meant to be, but thankfully, I got there and it is another good achievement for me."
