Andy Murray is hopeful of breaking up the dominance of Rafael Nadal and Roger Federer after becoming the first Briton to break into the world's top three.
The 21-year-old has replaced Novak Djokovic in the rankings after the Serb failed to defend his title at the Rome Masters earlier this month.
Murray said: "Rafa and Roger are probably the two best players ever so I'd love to try and break that up.
"The rankings reflect my good run and I just need to try and focus on winning."
Murray has surpassed the achievements of former British number ones Tim Henman and Greg Rusedski, who reached career-highs of fourth in the world rankings.
But he is aware that the next step, in breaking into the top two, is an even tougher ask.
"To get close, or in-between Roger and Rafa is tough," said Murray.
"They've held the top two spots for five or six years. It's an incredible run and Rafa has already won six Grand Slams.
"I just need to focus on winning matches."
Henman says Murray can go all the way to the top of the world rankings.
"The rankings don't lie and he's played so well since Wimbledon last year - there's no doubt in my mind that he's going to go higher and higher," said Henman.
"There's only two more spots to go but I really believe that he can be number one in the world one day.
"I think he's got every opportunity of winning slams because his game is developing so quickly and he's still so young."
Meanwhile, former world number one Andre Agassi believes Murray has the game to break into the top two and win several Grand Slams.
In an exclusive interview with BBC's Inside Sport, Agassi, who won eight Grand Slams, said: "Andy's a multiple slam winner, I think he'll win more than just one and he'll do it on at least a couple of surfaces.
"I love what he does out there, he's learnt how to focus, how to not interfere with himself but he's still kept that competitive edge.
"He has the movement, the athleticism, the speed and the wheelhouse of strike zone, when Nadal puts it above his shoulder Andy can still hit it pretty darn well and that's a big asset to have these days, being able to move forward on that ball even if it's above your shoulder.
"I like his match-up against a lot of different players.
"I think where he's going to be most likely to win first is the US Open.
"It's a surface that he can absorb pace so well and move the ball around so easily and he's a tremendous mover, especially on the hard courts."
