Andy Murray ready for US Open title defence

Reigning US Open champion Andy Murray admits "the memories came back" as he returns to the scene of his first Grand Slam triumph for this year's tournament.

The Briton won the 2012 title at Flushing Meadows after beating Novak Djokovic in a five-set thriller and has since added his first Wimbledon crown.

Murray says he is wary of "tricky" first-round opponent Michael Llodra of France.
