With all the injury problems we have in men's tennis at the moment, I'm happy to still be standing.

I'm playing great tennis. I'm enjoying the tour, having fun with the fans off the court. I'm loving it now.

I can walk around screaming, 'I have 17 Grand Slams. I have the record here or there.' When you can play for history and you do it, that's what is so really cool, is that you can then be compared to other greats or you've passed another great, even though it doesn't mean you're better than him. But it's just like that moment you've gone into the unknown where nobody else has ever been before.

I think it's very hard for coaches to work with me. They'll no doubt have a good CV afterwards, but at the same time they're under a lot of pressure.

Tennis can be a very frustrating sport. There is no way around the hard work. Embrace it. You have to put in the hours because there is always something you can improve. [Y]ou have to put in a lot of sacrifice and effort for sometimes little reward but you have to know that, if you put in the right effort, the reward will come.

The serve, I think, is the most difficult, you know, in terms of coordination, because you got the two arms going, and you got to toss it up at the right time so.

My advice is you've got to make sure you wear the clothes and not [let] the clothes wear you. It's quite simple in a way. Don't wear something you totally feel uncomfortable with, but take some chances. Play around a bit. I felt very uncomfortable in suits when I was younger, so what I just started doing was wearing suits when I was going to dinner. I used to overdress a little bit so I got used to wearing suits. Now wearing a suit is like wearing a track suit for me. So it's all good.
