Laura Robson looks to Sloane Stephens encounter

British number two Laura Robson has said that she is in for a "tough" match against Sloane Stephens in the third round of the Australian Open.

The 18-year-old knocked out the eighth seed Petra Kvitova to set up a clash with the American, to whom she lost in the first round of the Hobart International last week.

"I definitely feel like I could play a lot better than I did last week, and it's going to be really tough, for sure," said Robson.

"She's in good form at the moment. She's a good mover, good ball striker.

"It's always going to be a tough match, but hopefully I can play better than I did today."

Robson is looking to reach the fourth round of a Grand Slam for the second time following her run at the US Open.
