US Open: Laura Robson confident despite defeat

Britain's Laura Robson says she has learned that she is able to compete at the highest level after reaching the last sixteen at the US Open in New York.

The 18-year-old lost 6-4 6-4 to defending champion Sam Stosur after becoming the first British woman to reach the fourth-round of a Grand Slam since 1998.

Robson adds that she was pleased with all the support she received, but a bit surprised by the attention she got from the media.
