Djokovic will find it difficult to maintain the winning ways, now that he is out of his prime.... All the greats struggled to win after 29 years age... Djokovic will now have to maintain his fitness and if there is one person at present capable of beating Fede's mark of 17, then it is him.
Nadal has fallen short in his quest of breaking Fede's records.... He looked well poised but for the last 2 years he is not even in the top 3 of the ranking.
There is only one greatest of all-time at the moment (GOAT) and that is Federer.
