Serena Williams: 'I've never played better'

Serena Williams has claimed that she played the best tennis of her career to win the gold medal at the London Olympics.

The American brushed aside Maria Sharapova 6-1 6-0 in Saturday's final on Wimbledon's Centre Court to complete the prestigious Career Grand Slam.

"I didn't think I would be this happy. Oh my gosh, I got the gold. Wow," she said.

"I've never played better. Playing against someone like Maria you have to be at your best. I knew that, so it was like I had nothing to lose.

"I have singles, doubles, actually everything there is to win in tennis. Where do I go from here?"

Williams is also the first player in the history of the game to win the Career Grand Slam in both singles and doubles.
