Australian Open: Andy Murray to prepare for night conditions

Andy Murray says he will practise playing "under the lights" ahead of his Australian Open semi-final, which is scheduled to take place at night, something he has yet to experience at this year's tournament.

Murray explains that "the court is slower" and "rallies are a little bit quicker" in night conditions.

The third seed progressed to the last four after a straight-sets victory over Jeremy Chardy and will be making his fourth Australian Open semi-final appearance in a row.
