The 33-year-old former England striker this week confirmed he would hang up his boots at the end of the season, having struggled to command a regular place at Stoke.
"It would be wrong to blame fitness," he said on his website. "It is either the manager's opinion I am not good enough or that I don't fit into the system."
Adding that he had "total respect" for Tony Pulis' decision to leave him out more often than not, Owen continued: "Considering retirement was a gradual process but I had come to the decision before Christmas that this would be my final season in professional football, although that wasn't quite the plan at the outset.
"I had signed for Stoke with every intention of playing more football than I had in recent seasons.
"Looking at it realistically, things are unlikely to change in the remaining weeks of the season. And having played so little in recent years, the chances of me continuing to play at the top level look remote."
