There's a bit of competition for places in the Test team now.
That's always been the case. I'm 34 now, so it's getting harder and harder to keep these youngsters out of the team. It's something I thrive upon. I always want to be the best at what I do and I'm going to keep working hard. I'm very confident I can keep doing well. You may find it amazing, as I haven't scored many runs in my last seven innings, but I've just had the best year of my international career. It shows I'm improving all the time, and I think I can get better and better.
If England were to retain the Ashes and then win the World Cup, would it be a suitable time to think about retirement?
That's way premature. I'm enjoying it more than I ever have, so why would I give up something I absolutely love? If I knew I was keeping young players out of the side who were better than me, then I'd have a good look at it. But at the moment I feel I'm getting better and better and I feel I deserve a place in the side. My mentality might change if we won the Ashes and the World Cup. I might think, "What else is there to do?" But that would be a massive achievement and I'm not counting any chickens.
