Murray has twice come close to ending Britain's 75-year wait for a male Grand Slam singles champion, but whether he will be able to finally end the drought is a hotly-debated topic.
He made a flying start to last year and was in the best form of his life as he made it through to the final of the Australian Open.
The British number one eventually fell at the final hurdle at the hands of Roger Federer but the signs were promising for the campaign ahead.
However, the tournament in Melbourne would prove to be the highlight of the season for Murray, whose next best Grand Slam result came in reaching the semi-finals of Wimbledon.
Dropping coach Miles Maclagan, with whom he had combined to reach the final at both the US and Australian Opens, also seemed to disrupt the 23-year-old for a period.
Murray did get back on track by the end of the year as he won the Shanghai Masters in October before impressing at the ATP World Tour Finals and will hope the momentum carries over into the New Year.
He has certainly started 2011 well enough, winning all three of his singles matches at the recent Hopman Cup.
