Andy Murray is the new top dog of men's tennis

Murray did something that no other tennis player has done and that's win the World Tour Finals to end the year as world number one. And he did it in grueling fashion with epic matches against Nishikori and Raonic, the latter being the longest match in tournament history. And then he beat a fresher Djokovic, who had a significant advantage over him in head-to-head. It was a remarkable feat and one that would have been talked up more if tennis hadn't lost some its lustre in the post-Federer/Nadal era.

Andy Murray has a lot more success than Stan. He has at least 10 masters; two Olympic golds, and yes, while he has the same no. of GS wins as Stan he has constantly been a finalist at the Slams. And he has held the no.2 ranking for a long period - only dropping to no. 4 following his back surgery and subsequent recouperation.

Well deserved, he's easily been the best player for the last six months. Could still end up at No. 2 if Novak wins the year end tournament. What a year for firsts - Leicester city, cubs, western bulldogs, Ireland over the All Blacks and now Murray after being the longest running No. 2. As an aside - has there been a more hideous cup than the Paris Masters one? Looks like something my Aunt Bertha would've placed on her mantle after a day hunting through garage sales.

Has quite a few more finals appearances though and Stan has never risen above No. 3

They have Kyle Edmond, who is rising in the top 50 and Dan Evans just outside it, not to mention Konta in the top 10

I think we are about to see a crisis in men's tennis. There is no young players coming through. It's pretty much the old guard who are slowly falling apart. And that's probably why Murray is number one. He is the only one standing at the present time from the old guard. Interestingly, Murray was always regarded as part of the big 4 with Federer, Rafa, and Novak. And yet, Murray has the same grand slam titles as Wawrinka, which is 3.

This looks like the weakest point in mens tennis ever coming up. Murray hasn't risen to no 1, by being a late bloomer, he is there becuase he hasn;t fallen away physically as much as Djokovic and there is no one younger coming through.Look how many old players are in the rankings over young ones. Djokovic benefited from Nadal and his physical woes, with Nadal having such a hard game on the body. You have Djokovic and Miurray both 29 , have a massive points lead over the rest and then its Wawrinka 31. Raonic 25 being injured is not a good sign for him. If Murray and Djokovic get injured then anything could happen including Kyrgios becoming no 1 in between wearing a straitjacket.

How many other tennis players they have ?

Murrays rise parallels GB's rise to a sporting super power. Although I think he is a miserable Git , I commend him on his talents and hardwork .

I meant this thing trotted out about the UK media referring to him as a Scot if anything bad happens and GB if it's good. Don't worry I wasn't being narky (although on reflection it looks like that!). I just don't think it's the case. I think it's joked about but never was a "thing" I'm a long time Roarer , v infrequent commenter , previously lived in Oz for several years but back in U.K. for sometime now. PS I like your succinct columns with a point and and,most importantly!, an opinion, you probably thought I was one of the usuals laying into you and not your opinion.

"Throughout his career Murray has been tabbed a Great Brit when he does something spectacular, and a Scot when he doesn’t." He hasn't
