French Open: I'm in amazing form - Serena Williams

World number five Serena Williams describes her current form as "amazing" as she looks forward to the 2012 French Open, which begins on Sunday.

The American won the Grand Slam event in 2002, and following her recent win at the Madrid Open, many pundits are backing her to be victorious at Roland Garros this year.

Speaking to BBC Sport's Jonathan Overend, Williams also says there is "a lot of depth" in women's tennis now and believes the French Open will be very competitive.
