"It's one of my biggest titles so far, biggest achievement". 'All of a sudden they do not happen for a while.
Federer's down the T serve was returned well by Djokovic straight in the middle and the Swiss ace took his time before whipping it to Djokovic's right to what looked like a sure victor. And when they happen, you party like a rock star.
"I don't want to talk about that".
"It depends on how I'm playing, how my body feels".
The 22-year-old Khachanov, ranked 18th, is the first Russian to win here since Nikolay Davydenko in 2006.
What was most impressive about Khachanov's victory was the manner in which he bullied Djokovic around the court with the depth and booming accuracy of his groundstrokes and his confidence in his ventures to the net.
Khachanov became the third different first-time victor of a Masters tournament this year - joining John Isner and Juan Martin del Potro - and denied Djokovic a fourth title in a row ahead of his return to world number one on Monday.
"For the most part I can be happy, my level was good, but losing is never fun", said Federer.
Yet even though the Serb may also have been suffering from the after-effects of his epic three-hour 7-6 (8-6), 5-7, 7-6 (7-3) win over Roger Federer in the semi-final on Saturday, nothing could be taken away from the outstanding quality of Khachanov's attacking game.
"I want to talk about how well (Khachanov) played all week and absolutely deserved to win today", Djokovic told reporters.
Khachanov added this title to the Kremlin Cup in Moscow last month for his third title of the year and fourth overall.
Djokovic outlasted Federer in an energy-sapping classic that lasted over three hours on Saturday, and the Serb began to look tired as he dropped serve to a fall behind early in the second set.
"After that, my intensity (changed), I stepped in more inside the court, started to move him and maybe he didn't expect that", said Khachanov, who did not give up another break point in the rest of the match with his pinpoint, heavy serving.
"I'm satisfied of course and I'm going to be No. 1 tomorrow. I mean, I won 20-plus matches in a row and had a most awesome last five months", he said.
"Two years isn't a lot in most people's lives, but for me, there's a big difference between 37 and 39".
