It was rather obvious Nadal had no answers to Djokovic and he was so scared to use his back-hand such was Djokovic's dominance and i was astonished at one time Rafa's forehand collapsed completely. Rafa needs to see a game out if he is holding serve and this is where the mentality comes in,it was quite clear Djokovic was stronger mentality and it was always a tough ask for Nadal not mentioning Djokovic had endured a 5 set thriller against Foger and this too alot away from him which makes this win all the sweeter.
On Serena it was understandable not acceptable since it was 9/11 memorial on home court on a grand slam final and in my view the Umpire should have replayed the point thatn award the point to Sam.it was a big big call by the umpire on a game of such magnitude.
The greatest danger in times of turbulence is not the turbulence; it is to act with yesterday's logic.
