World No. 1 Novak Djokovic underlined that Kei Nishikori wasn't an easy opponent to play though he thrashed the Japanese. Djokovic, who is aiming to win his maiden gold medal, demolished former world No. 4 Nishikori 6-2 6-0 to reach the Tokyo Olympics semifinal.
Djokovic has been clinical so far in Tokyo, winning all four of his matches in straight sets. "Matches are not getting easier, but my level of tennis is getting better and better," said Djokovic, per the ITF website.
"I've done that many, many times in my career: I know that I'm kind of player that the further the tournament goes, the better I'm feeling on the court. That's the case here: my best performance of the tournament tonight against the very good opponent.
"Kei, I know his game very well. Him playing in Japan, this court where he had lots of success, I knew that he's going to play very quick and he's not gonna give me a lot of time so I had to be very alert. And I feel I had an answer for everything he had."
Nishikori failed to deliver something 'extraordinary' against Djokovic
"Djokovic is the strongest player in the draw. I've been playing well this week, I want to keep that good feelings and take a full swing.
I have to play well with something extra, otherwise I'll lose," Nishikori said prior to the match. "I'm getting better, only that gives me confidence. (If I had had to play with him) several months ago, I'd have had no confidence.
Finally I've started making decent rallies, feel like I can clash with him to some extent." Djokovic made a perfect start to the match, having taken an early 3-0 lead. Nishikori saved a break point in the sixth game to reduce the deficit to 4-2 but then dropped the following eight games as Djokovic booked a routine win.
