It's strange. The unseeded Kyrgios made the statement, "I felt like he didn't do anything fantastic today," 

which some may not agree with considering that Djokovic amassed 31 wins and only eight unforced mistakes over the last two sets while facing zero break points during that time.

But he just seemed so cool. I was just thinking to myself that. It just seemed as though he was unfazed in crucial situations.

He simply never seems rattled, and I think that's his biggest strength," said Kyrgios, who probably hasn't heard himself say such things. 

"He simply keeps an inward gaze the entire time. Despite the fact that it seemed like he was playing large, it didn't appear as like he was playing too aggressively.

The top-seeded Djokovic was pleased to hear some Centre Court spectators chanting his nickname, "No-le! No-le!," as he served out the final point of an incredibly well-played tiebreaker.

"The more you win, it's logical the more confident, the more comfortable you feel out there every next time you step out on the court," said the Serbian.

For the time being, Djokovic won't be able to attempt to catch Nadal by winning the US Open, which gets underway in late August.
