World No.2 Andy Murray has revealed that he has 'not been sleeping great' ahead of his quarter-final clash against rival Kei Nishikori. The Olympic Gold winner has also praised the Japanese star, and he knows that he will have to deliver his best to win against the World No.8 on Wednesday.
"I've not been sleeping great since I've been here. I don't know why.
"On Sunday night I tried to get
The 29-year-old has dominated the head-to-head record against Nishikori beating him seven times in eight meetings so far. The duo faced each other in the semis of the Rio Olympics, where the Brit defeated the Japanese star 6-1, 6-4. The only time Nishikori has defeated Murray was back in 2014 at the ATP World Tour Finals. However, Murray knows that Nishikori is in good form, and he will have to perform at a high level to get the better of him.
"I played a really good match against Kei when we played a few weeks ago. I'm aware I'll need to do that again in a couple days if I want to beat him, because he's one of the best players in the world.
"I have played well against him in the past, but he likes these conditions. He plays well in New York. He's made his only slam final here. He beat Novak here (in 2014).
"He's obviously, I think, playing pretty well this summer. He played some good stuff at the Olympics and won the bronze,” Murray added.
Murray defeated 22nd seed Grigor Dimitrov in straight sets 6-1, 6-2, 6-2 in the 4th round of the US Open to reach the quarters. The World No.2 was pleased with his performance in the game. He said, "Grigor played his best but I didn't really give him a chance to get into the match. That's the beauty of an individual sport. Just because you play badly a couple of days ago doesn't mean I'm going to play badly tonight.
"My best tennis is in there. Not every day do you play your best. When you don't play your best and win, it's a really positive thing.
"A lot of people worry about that or panic, but you played one bad match. I won. I'm still in the tournament. I was able to play great tennis against Grigor."
