Pella reckons Djokovic will surpass big two's Grand Slam tallies
Guido Pella says Novak Djokovic will win more Grand Slam titles than Roger Federer but tennis fans will decide who is the greatest.
Pella, who compared Federer to Lionel Messi and Rafael Nadal to Ronaldo in the same ESPN interview, expects Djokovic to outshine the pair of them by the time he calls a halt to his professional tennis career.
The Serbian won his 16th Grand Slam title at Wimbledon this summer and is now just four behind Federer and two back off Nadal, who added his 18th at the French Open in June.
"For me, Novak Djokovic will be the best in history by the numbers," said Pella, who reached the quarter-final at SW19.
"He will beat all records and he can win more Grand Slams than Federer. Now, that will not necessarily make him the biggest of all time, it's the people who decide that."
