Andy Murray has revealed his tactics ahead of his opening clash against Ryan Harrison in the Australian Open.

The 24-year-old will face his American opponent, who is known for his aggressive outbursts, tomorrow in Melbourne.

"I'll try to make him lose his temper early," said Murray. "It's something that helps if you know your opponent can get down on himself and it affects his game.

"And when you see them getting like that, you want to try to hit the gas and keep going."

Murray will have the hopes of Britain on his shoulders as four of his compatriots have already crashed out of the tournament.
