BBC Sport - Australian Open 2014: Andy Murray buoyed by progress after injury

My racquet bit the dust jokes Murray

British number one Andy Murray jokes that his racquet had to "bite the dust" when he smashed it after dropping a set in his four-set victory over Stephane Robert at the Australian Open.

Murray says his expectations at the start of the tournament were low, but describes his progress as a "good effort" after recovering from back surgery earlier this year.

The Scot faces four-time champion Roger Federer in the quarter-final and says it will be a "big match".
