Novak Djokovic meets Mikhail Youzhny on Thursday in the 2013 US Open quarterfinals.  The match is scheduled for 8 p.m. ET.  Watch the live stream HERE and HERE.

World No. 1 Djokovic has played well all season, but he appears to be getting hot when it matters the most.  The Serb hasn't dropped a set since beginning the US Open, and he's lost only 22 games through his first four matches.

"It's a fantastic feeling when you're playing this well," Djokovic told NY Daily News.  "You love spending time on the court.  ... It all comes at a great time to me.  I'm very happy with my mental state, how I played physically."

Djokovic is the favorite to win on Thursday, where he'd likely advance to meet Andy Murray in the semifinals.  If he survives that clash, longtime rival Rafael Nadal would likely await in the final.

Djokovic, however, insists he's not concerned about who he might face down the road.

"I really don't pay attention to my opponents during matches," he said.  "I have this very determined vision of what I have to do on the court."

Opposite of Djokovic on Thursday will be Youzhny, the No. 24 player in the World.  The 31-year-old Russian is 31-18 for the season with the Swiss Open title to his name.  He's dropped only three sets through the first four rounds of the US Open, earning a spot in the quarterfinals on Tuesday with a five-set victory over Lleyton Hewitt.

Djokovic has won five of the eight matches he's played against Youzhny.  They last met in the second round of the 2013 Monte-Carlo, where the Serb won in three sets.
