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

When I was younger I always wanted to impress, to be good for my country, to make them feel good, and sometimes that meant I didn't focus on myself enough. I learned I had to put myself first. And it's fine because I want for me the same thing that they want for me, which is to win.

When people see your personality come out, they feel so good, like they actually know who you are.

I have to show who I am, play with the crowd, play with the camera. When people come to a race, part of it is the anticipation, "What is he going to do?"

There are things that bother me. I try not to let them, but they do.

I can't watch a [Floyd] Mayweather fight. I don't find it exciting. I used to watch boxing in the [Michael] Tyson era when it was exciting. Now it's all bob and weave, a punch here and there. It is not entertaining.

I always support Argentina. I watched a lot of the European Championships but wasn't supporting one team. I knew some players in a few of the teams and was just seeing how they played. It was nice for Ronaldo to win with Portugal.
