Cape Town - The debate surrounding the greatest tennis player of all time tends to involve Roger Federer and Rafael Nadal - but Richard Krajicek reckons the real GOAT is Novak Djokovic.
Krajicek, who won the Wimbledon title back in 1996, acknowledges that Federer has won six more Grand Slam titles than Djokovic, but believes the Serb has competed at a higher level than Federer throughout his career.
"When you look at the results and length of his career, you say Roger. But when they play at their best each other, Djokovic is the better player and he wins most of the times," said the Dutchman.
Krajicek also reckons that Djokovic has pulled off the most impressive feat in tennis by holding all four Grand Slam titles at the same time, which he achieved in 2016 after winning the French Open.
"He is unbeatable in the level of tennis. Novak had two or three amazing years. Federer played for 20 years at the top, his consistency is incredible. But Novak has won four Grand Slams in a row, which Federer and Nadal have not done."
Krajicek is the tournament director at the Rotterdam Open, and would love to see Djokovic return to play in the ATP event.
The Serb last played Rotterdam in 2010, but has reserved the month of February for Dubai or Acapulco ever since.
"We would like to have him as a world No 1. It's a tournament that doesn't fit in his schedule. He is winning basically everything and we will always keep trying. If he wants to play Rotterdam, the doors are open," Krajicek added.
