Stoke City striker Michael Owen has explained why he's retiring.
At 33, Owen admits he could continue playing, but he is not keen to play beneath the top level.
"I have no doubt I could keep playing but it would not be at the level I would want. Once you have played at the highest level, it is difficult to drop down," he admitted.
"Many injuries took their toll and robbed me of my most lethal asset, which was my pace early on. Some of those injuries hurt me - but I am proud of playing at the highest level at the death."
