LONDON: The debate over the Greatest of All Time (GOAT) in men’s tennis has divided opinions for years but American Pete Sampras has no doubt that Serbian Novak Djokovic is the one. Djokovic, Roger Federer and Rafa Nadal are currently tied at 20 major singles titles each and fans and pundits have continued to argue over who should be considered the ‘GOAT’ Djokovic, at 34, the youngest of the triumvirate, has been unmatched in consistency and success in recent years and has already claimed Federer’s long-standing record for holding the men’s world number one ranking for most weeks. This month the Serbian broke a tie with his childhood idol Sampras by clinching the year-end world number one ranking for a record seven times. “Seven years, for him, I’m sure he sees it as a bonus to all the majors that he’s won,” Sampras, who won 14 major singles titles before retiring after the 2002 U.S. Open, was quoted as saying by the ATP Tour website. “But I think he’ll appreciate it more as he gets older. He did it at a time where he dominated two of the greats, in Roger and Rafa, and he handled the next generation of players very well — all at the same time. I do think what Novak’s done over the past 10 years, winning the majors, being consistent, finishing number one for seven years, to me it’s a clear sign that he is the greatest of all time.”
