Serena Williams: 'Victoria Azarenka should win'

Wimbledon champion Serena Williams has said that "on paper" Victoria Azarenka should win their Olympic semi-final this afternoon.

The American does however enter the encounter as favourite because of her recent form, especially on the grass of Wimbledon.

Speaking ahead of the match last night, Serena said: "Victoria has been playing well, she had a solid win. We both are playing well.

"She is the top seed and number one and on paper she should win, so that makes me be able to relax more. It will be a good game."

The duo are also both still in doubles action at the Games, with Serena in the women's doubles last four with her sister Venus, while Azarenka is in the mixed doubles quarter-finals with Max Mirnyi.
