Li is lucky to get Carlos coaching. Li's problem has been mental, more than technique, always hot and cold with lapses and not able to focus consistently . Carlos was right to the point, she can't let her heart and emotions rule her mind, it has to be the head in control so she can see the road ahead. The on court coaching was so obviously that when Li just executed the orders, everything came together in her game. It's lively to see Carlos back in the players box!
It's amazing what a great coach can do to a player. Since he started emailing from the first match in Rogers cup (even though he was not physically there) , the messages got to Li during the tournament and she got to final. If Carlos was there in that final I think she would have beaten kvitova.
