Australian Open: Andy Murray looking forward to Dimitrov clash

Andy Murray is expecting a tough test against Grigor Dimitrov after comfortably making it into the last-16 of the Australian Open.

Murray beat Portugal's Joao Sousa in straight sets to set up the clash with the Bulgarian, who knocked him out of Wimbledon at the quarter-final stages last year.

Murray puts that defeat down to a "bad day" at the office and says he is fully prepared to take on Dimitrov in Melbourne.
