I don't get nervous anymore. The first couple times I met Roger Federer, or Grigor Dimitrov, I was a little nervous. But now, it's more natural.

There are not many times when I get nervous, but I do a little bit with penalties.

Every win that I've been going through, it's been securing anyone's doubts or even my own doubts about whether I belong with these guys, playing these high-level tournaments.

I'm very sorry to Mr. Gabas, to whom I apologised in person. Very sorry for letting my Davis Cup teammates down and for letting my country down. I apologise to all the tennis fans, to my supporters, and my sponsors. I feel ashamed of my unprofessional behaviour and will accept any consequences as a result of my action.

I never assumed that I would be able to play in a main draw so quickly after Juniors. I've been having really good results. It really is a privilege. I'm very happy for the opportunity.

A lot of it's mental - a lot of the juniors, once you break them or change the momentum, they go away very quickly.
