Novak Djokovic says that tiredness cost him the Wimbledon title after losing to Andy Murray in the final.
World number one Novak Djokovic believes that his defeat in the final of Wimbledon was partly down to his demanding semi-final clash against Juan Martin del Potro.
The Serbian took four hours and 43 minutes to defeat the Argentine on Friday, just two days before losing to Andy Murray in the final at SW19.
"I cannot look for excuses but the previous match took a lot out of me," Djokovic told reporters.
"I've been in these situations before. I felt okay but maybe physically I didn't have enough gas in the important moments.
"It was a very long match for three sets today. But the bottom line is that he was a better player in the decisive moments."
Djokovic has won six Grand Slam titles in his career so far.
