Djokovic - no debate. Holds a positive record against Federer and Nadal and dominated the sport for over a decade.

He does not have the better stats over Nadal and Federer when all 3 were healthy in their prime in top form which is before any reached 33 yrs old. Look at the head to head and major count during that period I just mentioned and you'll see when we compare apples with apples Fed is #1 Nadal #2 and Novak #3
