Today I read an article
in biggest Serbian daily about Michal Novotný, Czech guy who is introduced as the world leading physiotherapist for tennis who has been working with all top players (including Nadal) for years, and he still works with him. He was giving help to both Rafa and Nole in that Madrid SF recently...
Basically, article is retold interview, with quotes, that Novotny gave to Czech daily "MF DNes". So I found original
I know many "experts" have been saying the same about Rafa's knees for ages, but coming from this guy is something else, I guess...
Another interesting thing he told is that Rafa has very muscular legs which is fine, but his feet are small which causes problems.
