I really want to try soccer after I retire because I've watched football over the years and I think I could be a good contender.

I want to be one of the greatest athletes ever to live, not only in track and field, but in all of general sport.

I stay as far away from politics as possible, or any controversy.

Rio would be my last Olympics.

I still have the drive. I just want to push the barriers and see what I can do and how far I can go. I am just determined and driven.

We're not like the distance guys. I have a very simple approach. I don't overcomplicate. People ask me, are you doing 42 steps, 44 steps for 100 metres? I don't know.

Where I'm from, there is no violence, pretty much.
