Li Na (on being able to keep focus after Azarenka injured her back) Today the match is not about tennis, about fitness. Only about mentally. Because I thought maybe after the first set she will give up or retire, but she still try to continue to play.I think it's tough because I have to focus, hope all time, because you never know what happen on the court.

Victoria Azarenka (on why she insist on staying in the match after the injury) Well, there are a few reasons why. Because there is no win situation here retiring, and, you know, being all discussed retired, and the other thing is just try to do the best. I don't have a tournament next week. The physio told me, they told me, You're really locked. There is no really structure damage, but you can't fix it that quickly. The most important, I just wanted to try to do my best for the fans who came and, you know, watched our match, for respect for my opponent. It was just about trying to do the most you can out there.

Angelique Kerber (on keep up good momentum since the US Open) Yeah, after the tough loss in Wimbledon I played very well in the US Open and the Asia tour, so I think all this year I think I had a lot of good experience and new experience. So I think for the next season I will take everything with me and I have good preseason after my holidays, and I will prepare for the next season. So I think it was a very good year for me, and I'm still in the top 10 and I think that counts. I'm really looking forward to the next year.

Petra Kvitova (on her impressive third-set performance throughout the year): I wasn't that positive, how you said, but I was leading in the first set, but then I lost unfortunately in a tiebreak. The beginning of the second set was really tough. She had a lot of chances. I just tried to play my game, play some winners, and go for the net but still fighting, and I was still believing that I can play third set what I did a lot this year. So I was all ready mentally for the third.

Jelena Jankovic (on facing Serena in the semifinal ) I think first of all is the belief. You have to have the belief that you can win against her. That's the No. 1 thing, because she has that intimidating factor. Second of all, you know, that you have the game. You have to be able to stay with her, you know, power wise, you know, play smart, play my tactics right. I think she's a very powerful player, the most experienced player in today's game due to, you know, winning all the titles there are to win, being in the biggest stages in our tennis stage.

Sara Errani (on how difficult to make Championships two years in a row ) Very difficult. I know to be here is very difficult. I know it, but I'm ready to work, to fight every match, and doesn't matter how it be. I hope it will be good. But important for me always I say to fight and try my best. They are all so good opponent. We will see. I'm very happy to make these two Masters in these two years. I know it will be difficult, but I'm ready to continue. I hope to continue.
