The rankings in the tennis world change constantly as players vie for the coveted Grand Slam titles and newcomers enter the tennis world.
It is getting increasingly more difficult for the established older players to hang on to their crowns as the level of skill and expertise of the up and coming younger players is getting better and better.
Below are the current top ten ranked players in 2016.
The current number 1 is without doubt Novak Djokovic, he dominated in 2015 winning three of the four Grand Slams plus six Masters 1000 titles and concluded by claiming the season’s climax ATP World Tour Finals.
Apart from the French Open, Djokovic was unbreakable, he has already got 10 Grand Slams to his name.
The Swiss held winning records over the rest of the top 10 in the rankings in 2015 but at 34 there is only one player older than him.
While it may be difficult for Federer to repeat the success of the past year the veteran is still not relaxing changing his coach from Stefan Edberg to Ivan Ljubicic.
Already with two Grand Slams under his belt, Murray did not add to his tally as he finished year end no.2.
More significantly, Murray was instrumental leading Great Britain to it’s first Davis Cup title in 79 years. His involvement seemed to take priority on his personal play, but there still have been major disappointments at a fourth round exit at the US Open.
The past year has been tough for Nadal due to injury and psychological problems, as his steely confidence seems to have been shaken.
For the first time since 2004 he was unable to land a single Grand Slam title, but a strong performance at the ATP World Tour Finals does bode well for next season.
Wawrinka has another good season winning a second Grand Slam beating Djokovic at Roland Garros.
Since that victory, the 30 year old has been inconsistent, suffering convincing losses to Murray, Nadal and Djokovic.
A mixed season for the Japanese player, although winning three titles on the tour, he failed to make any serious impression at the Grand Slams.
He made his breakthrough in reaching the 2014 US Open final but has not made a Grand Slam semifinal in the past year. Still only 26 there is plenty of time for Nishikori to improve.
This season with his new coach, Berdych ended a seventeen match losing streak to Nadal to reach the semifinals of the Australian Open.
However, he finished the year adding just one more win over a player in the top ten. At the age of 30 it seems his chances are fading to win another another big tournament.
Although now 33, Ferrer is continuing to be present in the top ten for a sixth consecutive year. His overall fitness and stamina kept him at no.7 in the rankings.
It looks as though his chances of winning another Grand Slam have gone he is still good enough to remain in the top ten for some years to come.
Cilic unexpectedly took the tennis world by surprise by taking the 2014 US Open crown and then spent months out with injury. On his comeback he suffered another injury when defending his title and was crushed by Djokovic.
Avoiding injury, Cilic can be a serious contender once more.
Not a good season for Tsonga and missing out on the ATP World Tour Finals was a big disappointment. However, he did win the finals of the Shanghai Masters in October.
Tsonga has been inconsistent but has powerful weapons in his armory to defeat the best players around.
