Novak Djokovic: "I could not separate us"

Novak Djokovic has described his Wimbledon semi-final match with Juan Martin del Potro as "one of the most exciting" matches that he has ever been involved in.

The world number one eventually progressed to the final after a five-set battle with the Argentinian, which was the longest semi-final in Wimbledon history.

"It was one of the best matches I have been involved with. One of the most exciting, definitely," BBC Sport quotes the Serbian as saying.

"I could not separate us, apart from when I was 2-1 and a break up, and I dropped serve. That's why he's a Grand Slam champion. He came up with some top shots, credit to him."

Djokovic will face either Andy Murray or Jerzy Janowicz in the final on Sunday.
