Nadal: Work to be done

The Spaniard returned to Grand Slam action at the Australian Open having missed last year's US Open after his season was curtailed by injury and illness.

A quarter-final defeat to Tomas Berdych at Melbourne Park may not have been the result that Nadal had been hoping for, but the 28-year-old refuses to be too downcast, instead focusing on what lies ahead.

"It is not a bad start of season. I have reached the quarter-finals, and this is a good result now," he wrote on Facebook.

"I have accumulated a lot of matches,  and this is a positive thing for me, after all these months out of the circuit. I scraped together a lot of important points, whereas I will have a lot of them to defend in the next months. 

"The recovery process is not finished yet. I will continue to work with the right patience and desire, trying to lose less points as possible in the rankings."

The world number three is expected to return to action on February 16 when he begins the defence of his Rio Open title. The corresponding period in 2014 was one of great success for Nadal as he won titles in Mardrid and the French Open in addition to finishing as runner-up at the Miami Masters and the Italian Open.
