US Open: Andy Murray excited by Johanna Konta potential

Andy Murray says Johanna Konta has the potential to "go very high" after she reached the fourth round of the US Open by beating 18th seed Andrea Petkovic.

The British men's number one congratulated Konta on her "excellent run" which has seen her win 16 matches in a row, and set up a match against Petra Kvitova for a place in the quarter-finals.

Murray completed a straightforward win over Thomas Bellucci to move into the fourth round.
