REUTERS: Andy Murray believes that he can compete at the top level for only another "couple of years" even though Roger Federer has proved that it is possible to win major titles at the age of 35.
Despite the recent success of Australian Open champion Federer and 31-year-old Rafael Nadal, who claimed a 10th French Open title last Sunday, Murray believes that his physical condition and fitness could limit his performances in the future.
"I know some of the players have been doing really well until their mid-30s recently... maybe the next couple of years are the last few where I have a chance to compete for the majors and the biggest tournaments," the 30-year-old Wimbledon champion told the BBC.
"Most of the players are travelling with physios now, spending a lot more time working in the gym to protect their bodies from the kind of pounding you give it on the court as well. I think some of that explains it.
"I don't know how long I'm going to be playing for any more. I want to make the most of every tournament I compete in... I'll continue to play so long as my body is fine."
The Briton, who has won just one tournament this year, believes that the experience gained over his 12-year professional career helps him deal with the pressure during Wimbledon.
"For me, it is obviously always going to be the biggest tournament during the year," Murray said.
"A lot of pressure comes with it as well. There's a lot of expectation during this period, so it can be a bit stressful...
"I'm older and more experienced in dealing with it. The pressure and stress that goes with it maybe doesn't affect me quite as much when I was younger."
Murray will start the grasscourt season at the Aegon Championships at Queen's Club, where he faces British number four Aljaz Bedene in the first round.
