Rihanna, Beyonce and Nicki Minaj - we may not win, but we would have a lot of fun [in 4x400m relay team].

People always say I'm a legend, but I'm not. Not until I've defended my Olympic titles. That's when I've decided I'll be a legend.

There's a lot of great Olympians, but for me, I try to prove myself as one of the best - and that's the key thing.

Since they came in with the selfie, it's the worst thing. You hardly ever get asked for autographs any more. It's always selfies.

Unfortunately, I don't usually get to see much outside the Olympics as I compete almost every day. I have been to Rio a few times and got a tour of the sites. It is a spectacular city.

Every season something happens so I programme that in; something will happen.

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