Andy Murray made a strong start to his Australian Open quarter-final against Jeremy Chardy, taking the opening set 6-4 in 44 minutes.

The world number three was in control early on before having to withstand a fightback from an opponent who appeared initially nervous on his first appearance in the last eight of a grand slam.

The Frenchman tossed in two double faults in the opening game and then netted a high backhand volley on break point to gift the Scot the initiative.

Chardy came into this match having hit the most forehand winners in the tournament and it was no surprise that Murray continually probed the backhand in the early exchanges.

It was proving a smart tactic as another weak shot off that side at 0-2, 30-40 allowed Murray a simple volley and left him a double break to the good.

A booming ace finally got Chardy on the board before he got one of the breaks back as Murray netted a routine sliced backhand of his own.

Chardy was finally starting to warm to his task but, despite getting to deuce with Murray serving for the set, he could not find a way through as the US Open champion edged in front.
