Juan Martin Del Potro has played down suggestions that he will not be fit for his Wimbledon semi-final with Novak Djokovic on Friday.
However, Del Potro may be buoyed by the fact that he came out on top the last time the two met at the All England Club - in the bronze medal match at last year's Olympics. Djokovic added: "He is a quality opponent. There are no real clear favourites now in the later stages of the event. "But inspiration is out there, you know. Of course you always want to do your best in the grand slams."
