There's that talent thing where I can score goals, and there's also that want and ambition to keep doing it and doing it and doing it. I've seen a lot of players do it for a year and then they rest on their laurels, but I've been very driven throughout my career. Without being the most talented, I think I've tried to make the most of it.

Goals never come easy. No one gives you goals.

I always dedicate my goals to my mum. I lost her a couple of years ago. She was my biggest supporter and is always with me.
