Slade is really complicated. First he hated Rafa, then Novak and now back to Rafa. And since his hero just beat Rafa to win his long-waited 18th slams, fixed the poor head to head and leaving little chance for others to surpass his record, so I find it hard to understand why he still hates Rafa that much ?
Slade just wants Federer's legacy and slam tally to be secured at the top where it rightfully belongs.
Nadal is a man who is dangerously close to catching Federer's number. He is also the cause of many heartbreaks and slam losses for Federer over the years. Nadal also plays a brand of tennis which Slade deems to be a violation of the good spirit of the sport.
Djokovic is an interesting case. He has taken Nadal out of many tournaments and grand slams, evening denying Nadal a NCYGS. Things were going great until recently when Djokovic started to deny Federer of slam titles. He had overstepped his mark and was now interfering with greatness, an area of which he had no business.
Now that Nadal is back to his clay heights, he is looking very likely to add to his slam count. Djokovic is one man who can rise up and tame the bull from biting another La Coupe des Mousquetaires.
