World number four Andy Murray has claimed that the failures of fellow British players are not his problem.

Murray's win over American Ryan Harrison meant that he was the only British winner in the first round of the Australian Open.

The 24-year-old said: "I'm not the person to be disappointed about that. There are other people in charge that should be disappointed about it, not me. I mean, I'd rather there were more Brits winning, obviously, but it's not for me to be disappointed."

Murray will face Frenchman Edouard Roger-Vasselin in the second round.
