Interestingly, Nadal now leads the tour in 2017 with match wins (32) and although Djokovic is higher ranked (World #2) and the defending champion here in Madrid, he has been having a very rough year, and recently fired his longtime coaching staff.
As a result of winning their last 7 meetings, Djokovic now leads his head to head with Nadal 26-23, one of the very few people on tour who can say that. If Djokovic were to beat Nadal on clay, it will probably resuscitate his entire year. It is a widely anticipated match, but I give the edge to the Spanish King of Clay right now. But it will be a very tough battle.
MadProfessah's pick: Nadal in 3 sets.
