"I believe I can get there. I definitely believe I can get there," said Andy Murray of the prospect of becoming the world's best male tennis player.
"These last few months have proved that to me.
"I may never get another chance to be number one, so I'll give it my best shot to do that while I have the opportunity."
What's the deal?
Murray is closing in on the current world number one Novak Djokovic on the Emirates ATP Race to London. He trails the Serb by 915 points.
His comments that he "can get there" came in the wake of beating Roberto Bautista Agut in straight sets to win the Shanghai Masters.
