Asked if he could see himself still playing at 40, the 38 year said,: "I don't see why not. I really don't see why I should start putting a ceiling on things.
"The 2010 World Cup would be a great target, of course, I would love that but why put barriers up or have an end point?
"I have always said I will play as long as I can and I'll make myself available for as long as I can.
"As long as someone keeps picking me, I'll keep turning up.
"I'm enjoying it, even if people keep telling me how old I am and how I don't have long left!
"I just play it as I see it, taking things week by week or day by day rather than thinking about next season."
