Kyrgios said he was impressed with Murray's athletic prowess, and said he spends time just staring at the British world number two in the locker room.
After Kyrgios summoned two unreturnable serves, Murray's running forehand handcuffed him at net, and he couldn't land the volley that would have brought the game to deuce.
Murray was tormenting his opponent, though, one lob as he held serve to level things up, so teasingly played that in his bid to recover Kyrgios achieved the rare feat of knocking the ball clear out of the arena.
This was the most eagerly-anticipated match of the fourth round and the first real test of Murray's title credentials.
"I don't know." Kyrgios was asked if he felt he was at a crossroads in a career which two years ago seemed destined for the heights after he knocked Rafael Nadal out of Wimbledon.
Though it's day 10 of the tournament, Wimbledon officials are rather confusingly insisting on calling it Day 9 - with the "Middle Sunday" play officially designated in a sort of tennis twilight zone.
But I don't know what else to do with it. One week, I'm pretty motivated to train and play. One week I'll just not do anything.
The former world No. 8 was saddened by comments from Kyrgios after the match in which he said he was "too soft" to win a grand slam and "doesn't love tennis".
"Obviously I'm sure over time he'll start to do better and understand better how to deal with all of the attention and the questions".
Australian firebrand Nick Kyrgios revealed his softer side when he spoke in glowing terms about his next opponent, Andy Murray, saying it was "love at first sight" when they first met.
Meanwhile, Sam Querrey said fears his famous victory over Novak Djokovic would be labelled a fluke helped motivate him to beat Nicolas Mahut and become the first American man to reach a grand slam quarterfinal for five years.
The third set continued in the same vein as Kyrgios made some more freaky decisions and even refused to take his seat at the change of ends. "I don't really know a coach out there that would be pretty down for that one." he said, admitting to enjoying the freedom of doing as he pleases. "I couldn't compete today", said Nishikori. I believed that I could win the match.
"I try my best to win my matches and go deep as possible, but the matches get tougher as you progress".
"I showed how good I can play on grass".
That is Richard Gasquet at the bottom of your screen facing Jo-Wilfried Tsonga in an all-french encounter, only this match last just 24 minutes when Gasquet has to retire trailing 4-2 in the opener, because of a bad back.
Murray has an excellent record against 12th seed Tsonga having beaten him 12 times from 14 meetings.
However, nobody is playing better tennis than Murray right now.
