Grigor Dimitrov believes he has chance to upset world No. 1 Rafael Nadal in the Australian Open quarterfinals. The 22-year-old Bulgarian has reached the final eight of a major for the first time. He has played Nadal on three occasions and all have been three-set losses, including at Monte Carlo and Cincinnati last year.

“We all know that he has won tons of Slams,” Dimitrov said. “He's been a tremendous competitor. He's Rafa. We all know him. But that's what I'm playing for, to put myself in position to play those guys. I had tough battles with him in the past. Played a couple times on clay. There were always little things missing. But I'm quite happy with the way I'm performing so far. So I like my chances.”
