According to Jonny Wilkinson, his best days as a rugby player are still ahead of him.
Speaking to Setanta Sports, Wilkinson said, "If the enjoyment goes or I'm standing in the way of someone else then it's time to go but at the moment I'm feeling pretty good. I'd be desperately disappointed in myself if I didn't come back better."

"I have had more time to prepare, more to learn, I understand myself a lot better, I understand what I want and I'm enjoying it more than ever so why not? I'll carry on training as hard as I can to get better."
Asked if he expected to be fit to play a part in England's rebuilding, the Newcastle fly-half insisted that was his intention.
"Yes, definitely," said Wilkinson. "I think I've been misunderstood a little before. What I've said when I've been asked is that ahead of those representative honours, I'm just trying to make the most of my personal ability. I say, instead of asking 'What do I need to do to get back into the England side?', 'What do I need to do to be my best?'.
"I come back from the specialist the day before (England's February 7 opener) so I may have a bit of jet lag. There's stuff to do but I'll not be too far off then. When I come back from this injury I hope to be very active, then it's about getting match fit - the onus is then on you and I enjoy that responsibility."
