Serena Williams believes that her US Open semi-final clash against Li Na will be a "great match".
The defending champion got the better of Carla Suarez Navarro 6-0 6-0 in the quarter-finals.
"[Navarro's] a great player but the conditions were so tough and she definitely did not play her best tennis today," BBC Sport quotes Williams as saying.
"It's only because I've been playing here for like 50 years, so I've kind of gotten used to the conditions and even though it's very difficult to play each year, I'm getting used to it.
"I hope I'm not peaking yet, I'm just trying to do the best I can. I'm happy to have all this support and to be in the semi-finals feels great. It will be a great match against Li Na - she's playing some of the best tennis of her career and it will be a really tough match."
Li defeated Ekaterina Makarova in the quarter-finals to advance to the last four.
