My battery is finished: Nadal

Nadal limped out of the ATP World Tour Finals on Friday after losing 7-6 (7/5), 6-3 to defending champion Novak Djokovic.

Nadal concedes that he is feeling the strain of a gruelling and traumatic campaign that has been scarred by injuries to his knee and abdomen, as well as the separation of his parents.

“My battery is finished,” he said when asked how he felt. “Sometimes they finish and you have to buy another one! Only practising will help you come back to your best. That’s what I did all my life. I am gonna still do it.”
