After her Round of 16 win over Venus Williams, the always thoughtful Timea Bacsinszky had some high praise for a pair of her tennis idols, the 35-year-old Williams and Roger Federer.

Bacsinszky, who defeated the seven-time major champion for the first time on Wednesday, said she could hardly believe she had actually beaten such a legend. “I still sometimes cannot believe it, especially if you have a great win on such a good player,” she said. ‘I mean, she's definitely an inspiration, because if you see how long she is lasting as a tennis player it's something unbelievable. Even if she's struggling with health issues she's there, she's super nice with everyone, she's kind, and she's a great tennis player for so many years.

“So that's why to be able to win this match, my first win over Venus is -- well, it's just amazing.”

Later in her press conference, while talking about her own game, she threw some high praise to her compatriot Roger Federer. “Roger is an incredible source of inspiration,” she said. “He is 34 and last year he invented a new shot. I am not the new revolution. I don't want to invent a new shot for tennis, but I'd like to add more shots to my palette of shots.” The Swiss has reached back-to-back quarterfinals at Roland Garros and will face Kiki Bertens for a chance to make it back-to-back semis on Thursday.
