You are joking around here. Djokovic was injured in some of the matches or just dead on his feet like last year in Rome.2) Djokovic followed by Federer. Djokovic no longer poses a threat to Nadal on clay as evident by the last 3 matches seen. Federer was somewhat of a threat from 05-11 but not enough to beat him.
Nadal' stamina might have been supersonic till he was 32, but had he been in Djokovic's shoes last April, he wouldn't have won that match.
Anyway: past – Djokovic + maybe Fognini, present: Thiem (except RG) + Djokovic
