Novak Djokovic: "I played really well"

World number one Novak Djokovic believes that he "played really well" after overcoming fellow compatriot Viktor Troicki to reach the quarter-finals of Wimbledon.

The defending champion dropped just seven games in the 6-3 6-1 6-3 victory, but he has insisted that it was not an easy match.

"It is never straightforward. You always want to focus on every point because at this stage, the players are tough and the matches are getting more difficult," he told the BBC.

"I think I played really well throughout the whole match... I think I have played well the last three matches so I don't know what it is going to be like in the next challenge."

Djokovic will face either Richard Gasquet or Florian Mayer in the next round.
