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