Michael Owen has denied suggestions that he is injury-prone and insists he is fit and ready to be a success at new club Manchester United.
Owen, 29, put pen to paper on a two-year deal at Old Trafford on Friday evening after joining the Premier League champions in a surprise free transfer switch from Newcastle United.
The former Liverpool and Real Madrid striker has lost his England place during four injury-plagued years with the Magpies but is confident that his fitness problems are now behind him.
"I'd like to think that everyone was quite surprised with my medical," said Owen.
"I passed my medical and I've obviously passed them before and my fitness is high.
"A lot is made out of it but I certainly don't feel like I'm injury-prone."
Meanwhile, Owen has admitted he has a point to prove after making just 76 appearances during his four seasons at St James' Park.
"I've had a poor spell up at Newcastle but prior to that my career was very good - and I'm sure a top club like this can re-ignite my career," he added.
"I want to thank Sir Alex (Ferguson) for the faith he has shown in me and I give him my assurance that I will repay him with my goals and performances."
