Over the last four or five years there have been questions over whether Rafael Nadal is in fact the greatest clay court player of all time, or whether that title still belonged to Swede Bjorn Borg.

Whilst there is no doubt that Rafa is gaining fast on that title, whether he is actually the greatest clay player of all time is still in question.

Thanks to Rafa's shocking loss at Roland Garros three weeks ago, some people might have made the assumption that Rafa is not yet the King Of Clay, as many are already calling him.

Whether it is right to make such an assumption is unknown. Some argue that having six Grand Slams at 22 is a massive achievement, especially since arch rival Roger Federer only had one at the same age.
