Former world number four Tim Henman believes Andy Murray can climb to the top of the ATP rankings next season.
Murray is arguably the greatest ever British player to have graced the game, having won three Grand Slam titles and two Olympic gold medals.
The 29-year-old also guided Great Britain to a Davis Cup victory last year, beating Belgium in the final, and he is aiming to do the same this year, as the reigning champions prepare to face Argentina in the last four this weekend.
The Scottish star also added a fifth Queen's Club Championship to his collection in 2016 whilst winning the Italian Open, defeating Serbia's Novak Djokovic in the final.
Henman, a four-time Wimbledon semi-finalist, now believes Murray is at a stage of his career where he can challenge for the world number one position and feels the 2017 campaign could see it happen.
He told Press Association Sport: "I think it’s going to be difficult this year but certainly early next year he’s got a good chance. He didn’t play well in Indian Wells or Miami (this year) so come March or April time it’s going to be interesting.
"It hasn’t really been a realistic prospect for Andy before because the number one player has always been so dominant, be that Roger, Rafa or Novak. But over the last six months he’s not far off being level on points with Novak. He’s got a lot to play for."
