Andy Murray has admitted that he will have to be at his very best if he is to overcome Jo-Wilfried Tsonga in the quarter-finals at Wimbledon.

Murray is the highest seed remaining in the competition following Novak Djokovic's shock exit and goes into the last-eight clash in good form having cruised past Nick Kyrgios in the fourth round.

However, the world number two acknowledged that Tsonga poses another difficult test for him and insists that he will give the match his full focus.

"I'm fully aware of how difficult my next opponent is. I know Tsonga is one of the best grass-court players in the world. If he plays well, I'm not on my game, I can lose that match for sure. So I need to make sure I have a good practice, stay focused on that one. Take it one match at a time," he told reporters.

"I know everyone goes, 'Oh, that's boring'. But that's what you do as a professional. My job's to try to win my next match, it's not thinking about anything else. I think if I play the level I'm playing at just now, I give myself a chance in most matches.

"But the trick is to keep that up, to maintain that level for the whole two weeks. I've done a good job of it so far. I do feel like when I've needed to in the tournament, I have played some good tennis."

Murray is bidding to win his second Wimbledon crown having first won the trophy three years ago.
