So many players play Serena Williams, and so many players may catch her on a bad day, but she finds a way. She finds that extra gear. She makes it interesting, but at the end of the day, she come through in the end.

LeBron James is the best player, hands down. He is easily moving into the territory of one of the best players of all time and may end up being the best player of all time.

Give all the credit in the world to Angelique Kerber - great, great talent. She's been in the top 10 for the last four years, and she's one of those players that just really had a difficult time, when the chips were on the table, to kind of bring them over. And this time, she did it. I'm really happy for her because these chances don't come for these other players. Serena Williams has got 21 grand slam champions. Angelique Kerber was in her first final.

And to not blink against the greatest player in the world, I think she's going - she said it really nicely. She [Serena Williams] said now, I can call myself a grand slam champion, and that sounds really, really nice. So I'm very happy for her.

Don't make promises you can't keep.

I think nobody can explain why some people win and why some people lose. It really doesn't always have to do much with talent. It has to do with how you deal with pressure.
