What I think I've been able to do well over the years is play with pain, play with problems, play in all sorts of conditions.
You know, I don't only play for the record books.
Being a husband is for me as big a priority as being a father.
I went to Phuket already, but would love to go to Chiang Mai one day.
When you do something best in life, you don't really want to give that up - and for me it's tennis.
I have a very strong opinion. I'm absolutely against it. I'm against the challenge system. I'm for the way it is right now. Don't change that.
