The 34-year-old told The Times: "Football is inside me. If you live and breathe it and you love the challenge and want to see where you can go, you can't do nothing about it.
"I want to play for another three more years. I would definitely look at it after that, probably give myself a break, go away and start a family, but I think eventually I would like to come back and see what I can do.
"It's a shame people don't want to see the real you, that you're proper, that you've got no hidden agendas."
