Australian Open 2014: Andy Murray loses to Roger Federer

Number four seed Andy Murray says he did not expect to win the Australian Open having just returned from back surgery.

Murray lost 6-3 6-4 6-7 6-3 in the quarter-final to 17-time Grand Slam winner Roger Federer, having only played seven competitive matches since coming back.

The British number one was pleased with how his body reacted to such a tough match.
