It's really tough to call this one. Throughout this clay season, Djoker has looked like the 2nd best clay courter. He has had some very dominant victories and gave Nadal tough matches almost every single time. He certainly had his fair share of chances to beat Nadal at Madrid as well. Fed on the other hand ACTUALLY beat Nadal. He has also beaten Nadal once before on clay and has a winning H2H vs Joker on clay 2-1 (although Joker won their most recent match up). Going by results, I would pick Federer, going on form I would pick Joker.Thoughts?
