Is Del Potro Rafael Nadal's Second Biggest Threat at Roland Garros?

We all know that Novak Djokovic will be Rafael Nadal's private enemy number one for the next three weeks, but who is his second?

It may well be Juan Martin Del Potro, who announced his decision to play at the French Open this year. While he was sidelined last year, and has been until this week recovering from a muscle tear, his announcement will please many.

Let it be known - Del Potro is a force to be reckoned with. At one stage in 2009 he held a three match winning streak over Nadal, and, more ominously, has had great results on clay in the past.

A close loser in the 2009 French Open semifinal to Roger Federer, Nadal, and Federer too for that matter, had better been wary.
