Well, BG interviewing Rafa, Rafa said as close as he could say that he didn't think Melzer could pull this off, before the match either He was very careful with his words but you could tell it was disbelief that it was a 5 setter and Novak hadn't won yet.
Shock and disbelief! Huh? How do you begin to prepare for a semi against Melzer? Melzer who? Clearly he's playing with the urgency of a 29 year old in the twilight of his career who's never had a good result.
