"I thought he was actually doing fine until he told me, 'I think there will be some tears.' I'm like, 'Don't worry, it will be all right.' And he actually did. You know, in a way it was hard to watch, but at the same time I like seeing players who care for the game. I don't know. It's nice to see, you know. So you wish only the best for him."
On going forward: "I won't just put the entire calendar just around trying to win the calendar Grand Slam. I mean, it's something if it happens, it does, it's great; but it's not something that's like my number one goal. Not at all. It's the same as I haven't put a number on how many Grand Slams I want to try to win. Whatever happens happens.
"I really want to try to enjoy, you know, my end to my career, because I've reached already so many goals I thought were never possible. I really want to just enjoy the tour, and that's what I'm doing at the moment. Obviously as a dad as well even more so.
"But I try to be good for the game, leave it better off than when I arrived, even though that's hard. I'm very thankful to the legends of the game who created this great platform for us. We did have another record crowd attendance at the Australian Open.
