I saw a clip where they asked Jannik about his kit and it was so funny. He's a polite guy and was obviously struggling not to insult the Nike designers.
I've been flicking between the various matches, mostly watching Grigor vs Tomas Machac and Hubi vs Zizou. Both of which are really unfortunate first rounds for all concerned. Grigor and Tomas are both wearing the same shade of primrose yellow that Jannik was wearing when he won last year.
