Ivanisevic accepts that it comes down to a matter of opinions, but he believes Djokovic stands out above the others.
“Everything is important between the three of them,” he added.
“I mean – 311 weeks and more, it is fascinating. Novak has won everything that he could have won and the end of his career is not yet in sight.
“The GOAT debate comes down to taste and preferences, but if you have the numbers on your side, it is hard to deny some things.
“For me, Novak is the best and most complete player ever, for someone else it is Nadal or Federer.
“It will be an interesting topic to discuss when their careers are over.”
