London, Jun 29 (ANI): Andy Murray easily beat Sam Querrey 7-5 6-3 6-4 in the fourth round, but is worried that his other likely opponents are playing their best tennis.
Murray, 23, is the only male player not to drop a set so far in the tournament, but he knows he will have to get even better if he hopes to go all the way at Wimbledon this year.
The British No 1, who faces French 10th seed Jo-Wilfried Tsonga tomorrow, said: "It is nice not to have dropped a set and to conserve quite a lot of energy. I haven't had any long matches."
"But you have to remember Federer and Nadal are going to be playing their best tennis. Whether they have dropped sets early on is not going to make a difference to how they play in the quarterfinals and semi-finals,' he said.
"It's good to be in my third Wimbledon quarter-final. I came into the tournament not having been on my best run but I have got off to a good start.
"The next round will be tough as Tsonga has a big game and is a very, very good player," The Sun quoted Murray, as saying.
Tsonga insisted that the pressure will be all on Murray when they face each other. (ANI)
