"It was a complicated year, very good at the tennis level when I was able to play and at the same time very bad as far as injuries are concerned", Nadal said.
What Anderson can not ascribe to, however, is progressing further than fourth in the world, with the points tally of current number one Novak Djokovic, withdrawn, but still current number two Rafael Nadal and number three Roger Federer beyond the South African's reach - come what might.
But he has seemingly rediscovered his start of the season form, with a very good showing in Paris with impressive wins over Kohlschreiber and Dimitrov, and pushing Djokovic to the brink.
The second racket of the world Rafael Nadal due to injury will not play Final of the ATP tournament.
Nadal has pulled out of the season-ending ATP Finals because of an abdominal injury.
But once again, the limelight and the sport's biggest prizes were taken by the holy triad - The Big 3 of Novak Djokovic, Rafael Nadal and Roger Federer.
But he has time on his side - Federer has already celebrated his 37th birthday while injury-plagued Nadal is 32. Roger Federer has a big serve too'.
Meanwhile, reaching the final in London would rank alongside Anderson's US Open and Wimbledon final defeats against Nadal and Djokovic respectively as the most auspicious achievements of his career. The world No. 2 has not played since retiring from his U.S. Open semifinal showdown against Juan Martin Del Potro because of a knee issue.
The 22-year-old Khachanov defeated the 31-year-old Djokovic 7-5, 6-4, denying the Serbian superstar a chance to win his fourth tournament title in a row.
He was his usual dominant self on clay, collecting an 11th French Open title and three more titles along the way.
In Paris that year, he also became the first player to break through the $100 million (87.8 million euro) prize money barrier.
Nadal lost only four matches this year out of 49.
It looks like the best possible draw for Federer, who has added another remarkable year, winning yet another Grand Slam in Australia.
