Rafael Nadal was sad to suffer defeat to Dominic Thiem at the Australian Open, but insisted he was satisfied with his performance, as well as his attitude, in the quarter-final clash.
Thiem beat Nadal for the first time in six attempts at a grand slam with a tense 7-6 (7-3) 7-6 (7-4) 4-6 7-6 (8-6) win in four hours and 10 minutes on Rod Laver Arena.
The Austrian progresses to meet Alexander Zverev in the semi-final on Friday, while the world number one is left to reflect on a missed opportunity to draw level with Roger Federer on 20 major titles.
Nadal lost his trademark composure in the second set after umpire Auriele Tourte hit the 19-time grand slam champion with a time violation following a lengthy rally in the second set.

An unimpressed Nadal told Tourte, 'You don't like the good tennis' at the time of her ruling but rejected suggestions he was agitated throughout the loss at his post-match press conference.
"Honestly not, I was not frustrated," Nadal said
"I don't see myself with a negative attitude, during the whole match. I give myself all the time and opportunity, even in the tough moments."
The 33-year-old added of Thiem" "He's playing great. He's playing with a lot of energy, aggression, determination. So just well done to him.
"I honestly didn't play a bad match, no, no. My attitude was great during the whole match.
"Of course, I am sad. I lost an opportunity to be in the semi-finals of another grand slam. But I lost against a great opponent and he deserved it too.
"[I was] good, positive, fighting spirit all the time, giving myself more chances. That's what I tried. I did not give up in one moment during the whole match and gave myself an opportunity until the last point.
"Happy for that because my level of concentration and tennis was better. I think the concentration was even better than the tennis, but the tennis was not bad at all."
Nadal, who had 49 winners to 33 unforced errors and converted four of his nine break points, found the conditions difficult at times.
The Spaniard added: "It was difficult to play against him. [I'm] happy, but I need a little bit more determination in some moments - it's true that in some moments conditions have been a little bit heavy.
"Honestly, when the ball was new for me, I was better. I had two breaks and I felt more comfortable with the new balls.
"Then the ball became so heavy. He's younger, he's very quick. With these heavy balls, it's difficult to produce winners sometimes. He has a lot of power, so he's able to produce these amazing shots from a very difficult position."
Nadal, who only lost five fewer points than Thiem across the match, was asked if he felt there was any more he could have done to find a way to win.
"Yes - win any tie-break!" he said. "But that's how it works. Sometimes things are not going the way that you would like. It has been a very good match with a good level of tennis.
"I had a big chance with 5-3 in the first. I had set point serving. That was a very important moment of the match, for sure. Then I didn't play a good tie-break. I was back in the second set, but he played with the right determination.
"He played great matches against me in the past too, great quality tennis. We like each other in terms of character - I like his attitude and probably he likes mine too!
"We have things that we can compare with each other in some ways and I wish him all the very best for the rest of the tournament."
