Maybe for a guy like Zverev or Federer, you could say it's open a bit. For a guy like me, every match is tough, and I'm going to have to battle it out.

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.

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

You could say I'm a laid-back kind of guy.

I'm good when I've got a bit of an edge, like the Clint Eastwood type of archetypal character. The tough guy that doesn't say a lot.

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.
