In a recent interview with Marca, Ilie Nastase talked about the GOAT race between Federer, Nadal and Djokovic.
The first question was based around the number of won grand slam trophies with Nadal currently leading at 21 and of course, Nastase said if we're looking at it only from that angle it would be Nadal:
"If the greatest ever is the one who has won the most Grand Slams, the answer is
Rafael Nadal right now."
Then he further added:
"From my point of view, there are other factors that should be considered in this speech.
Roger Federer has an impressive talent and has helped to increase the popularity of tennis.
Novak Djokovic holds several records and was the great ruler of the game."
As with anything only time will tell who will emerge as the best of all time.
