Australian Open: Andy Murray opened his first Grand Slam since becoming world number one with a straight sets victory.

However, it was a far from easy task to overcome world number 95 Illya Marchenko.

Murray repeatedly looked to his bench for support as he struggled to find his form.

His Ukrainian opponent put up a fierce fight before Murray finally took the match 7-5 7-6 (7-5) 6-2.

The Scot is a five times losing finalist at the Australian Open and faces Russia’s Andrey Rublev in the second round.
