Tomorrow starts a new edition of Roland Garros and everyone is asking who will be new king of clay: Roger Federer or Rafael Nadal?

Until last year, Roland Garros was a big hat for Federer who didn’t manage to won it. When he won first time Roland Garros (2009), he already won 13  other Grand Slam finals. In all this time, Rafael Nadal was unbeatable on clay.

So this is a great opportunity to see if last year was only an accident and Roger Federer isn’t the perfect player on clay.
