Teenage sensation Nick Kyrgios will chase a "dream" semi-final against Roger Federer at Wimbledon on Wednesday.
The 19-year-old Australian felled world number one Rafael Nadal to reach his first grand slam quarter-final, where he will face Canada's Milos Raonic.
Kyrgios admitted he will face a battle to contain eighth seed Raonic's bullet serve, just a day after dispatching 17-time grand slam winner Nadal in four sets.
The Canberra native could meet idol Federer in the last four at SW19 if the seven-time champion sees off compatriot Stan Wawrinka.
Kyrgios played down John McEnroe's endorsement for the All England Club title, but admitted meeting Federer will offer fresh motivation.
"That would be extraordinary - if I manage to pull the win out against Raonic - to play Roger would be a dream," said Kyrgios, after his 7-6 (7/5) 5-7 7-6 (7/5) 6-3 victory on Tuesday.
Seven-time grand slam winner McEnroe told the BBC Kyrgios was "acting to me like he can win this tournament".
The all-action teenager refused to let his thoughts wander beyond facing Raonic, who saw off Kei Nishikori to reach the last eight.
"I'm just going to stay grounded," he said.
"Milos has probably got the best serve in the world.
"There could be a lot of walking side to side between points for me, so I have to work out how to deal with that.
"I'm just going to go out there and have fun again though."
Wild-card entrant Kyrgios arrived at Wimbledon ranked 144th in the world, and will now leave having reached at least number 65.
He is the first player ranked outside the top 100 to defeat a world number one at a grand slam since Andrei Olhovskiy saw off Jim Courier at Wimbledon in 1992.
Federer and Wawrinka will meet in Wimbledon's first all-Swiss quarter-final, with both men targeting SW19 glory.
Grass master Federer booked his 12th Wimbledon quarter-final with a commanding straight-sets victory over Tommy Robredo.
"It would be quite amazing to play Stan in the quarter-finals here too, that would be something for Switzerland that's for sure," said Federer.
"It feels great to be closer to the finish line than the start.
"It's only the quarter-finals, though, and that's where the tournament really starts ultimately."
Australian Open champion Wawrinka admitted he will relish taking on compatriot Federer, after powering past Feliciano Lopez in straight sets.
"It's going to be fun, I hope. On grass at Wimbledon, it's going to be something special," said Wawrinka of the last-eight clash.
"I'm happy with how I'm playing so far. It's going to be tough after two matches in two days, but I'll do everything I can to be ready."
