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.
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.
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.
I can remember watching Federer win Grand Slams on TV when I was a kid trying to put myself in his shoes.
A lot of it's mental - a lot of the juniors, once you break them or change the momentum, they go away very quickly.
There are a lot of very good juniors who have a very high level, but mentally, they're not quite there yet.
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.
