Yes, I've watched Chardy playing, singles and doubles, almost all of his performance, this whole Australian Open.
Come on! The guy only performed well in one match, the one that probably most of the guys who are hyping him saw, against Del Potro. And he choked pretty bad in the 4th and 3rd set.
He has a powerful serve and a big forehand, okay, but he isn't on fire that often. He can mentally melt with a blink of an eye.
