Most Grand Slam titles: Where does Rafael Nadal stand on list of most majors in the Open Era?

'Who has won the most Grand Slam titles' has become the benchmark for measuring tennis greatness, and Nadal's achievements certainly cement him among the finest players of all time.

If we are talking about the 'most Grand Slam titles' ever, then Margaret Court gets the nod. More than half of those titles were won before the Open Era, though, when professional players were not permitted to compete in them.

However, the Australian was a powerhouse in the Open Era, too, even reaching a Wimbledon final whilst pregnant in 1971.

Bjorn Borg is perhaps the ultimate 'burn bright, retire young' sports star in history. The Swede walked away from tennis at just 26, but he still had time to leave his mark.

If you are searching for some perspective about what Rafael Nadal has achieved, then consider this: If the French Open was the only Grand Slam Nadal had ever played, he would have still won as many majors as the great Pete Sampras.

The fact Nadal has achieved this while battling Federer and Djokovic only makes it even more remarkable. Should his foot hold out for a couple more years you'd have to back him to at least emulate Serena Williams' number of career Grand Slam titles.

It's ironic that we have grown obsessed about whether or not Serena Williams will break the all-time record held by Margaret Court when she already has the one that matters the most - the Open Era record.
