Britain’s Davis cup captain, Leon smith has warned current world tennis sensation, Andy Murray of the need to continue getting better if he is to tight grip and maintain his new heights on the ladder of world tennis.

Murray displaced Novak Djokovic off the ATP world ranking chart after beating him at this year’s World Tour final in London. Prior to that, the Serb had reigned as ATP’s crown prince for 122 consecutive weeks.

The best of the best in world tennis converge at the Qatar open come January 2 next year and Smith feels Andy Murray “…will absolutely work his socks off and try to get better again.”

Expounding on why defending a crown is harder than clinching it, Leon said: “You can go on an unbelievable run and go from number 100 or whatever but to go from two to one, it was 21 matches in a row at that level of the sport just to move one place.”

“Now he is number one he has got to work out how to stay there and improve again. It never ends never stops,” he added.

With Djokovic trailing Andy by 630 points, the Scot has a big chance of spending a very long time at the summit if he works hard enough as smith suggested.

Murray’s latest success has been nothing short of spectacular judging from the fact that as of June this year, Novak was way ahead of him by a massive 800 points but with the Scot’s impressive run of 24 match winning streak which culminated in an five consecutive titles, he now tops.
