The difference though is Fed is 5/6 years older than they are. How many slams will Nadal and Novak have in 5 or 6 years? I don't expect them to play as long as Fed has but they will win more slams for sure. Fed at 38? Unlikely, 1 more max imo.more slams ? They each won only one more than Fed so far. Fed has 4, Djodal have 5 each. Do not know what you are talking about.
Nadal was constantly underestimated and denigrated by the tennis media, always for Fed's benefit.And the crazy thing is Fed is already 38 and they are 33 and 32 and have already won more slams after 30. I still remember folks saying Nadal would be finished winning slams by age 24 because of "his style of play". Has to be one of the worst tennis predictions of all time.
