World number three Stan Wawrinka insists that he will not follow in Andy Murray's footsteps and reach the top spot in the ATP rankings.
The Swiss star has been quick to praise Murray since he surged to the top of the rankings following his win at the Paris Masters.
He replaced Novak Djokovic but the Serbian is still hoping to finish as world number one if he wins the season-ending ATP World Tour Finals in London.
Wawrinka has three Grand Slam titles to his name, including this year's US Open but he still claims he will never reach the world number one spot.
"Andy is a special player. He's part of the big four. He's been fighting with the three others to win Grand Slams, it's not like I never expected him to be No 1.
"I don't think so. Right now I'm 31, I'm number three, in the top four for the last three years, so it's already something really special.
"I know I can beat every player, I need to do it more often in the year if I want to think about that, but so far I'm way off that."
