Serena Williams has declared that she is ready to go for back-to-back success this summer at Wimbledon as she prepares for London 2012.

Williams won her fifth Wimbledon singles title earlier this month and will be back at SW19 next week to take part in the Olympic tennis tournament.

At a news conference with Team USA, Williams confirmed that she is ready to perform.

"I feel really good going into these Olympic Games, and wanting to do really well, I expect to do well," Williams said.

Serena and her sister Venus will expect to be defending their gold medal in the women's doubles, but team officials will not pick players for doubles competition until next week.
