Rafael Nadal faces fight to revive ailing tennis career
The French Open champion will need to summon his indomitable spirit to overcome his knee problems and play again in the new year
Rafael Nadal heads into 2013 with his career in freefall and needing to summon up the no-surrender spirit that steered him to 11 grand slam titles, the world No 1 spot and US$50 million in prize money.
The 26-year-old Spaniard hasn't played since June and on Friday he announced that he would skip the 2013 Australian Open because of a stomach virus.
But many in the sport believe that Nadal's lengthy battle against knee injuries, which have plagued his career and kept him off tour since his shock Wimbledon second-round loss to world No 100 Lukas Rosol, remains his prime concern.
"He told me he's not 100 per cent right now and wants to wait a little bit," said compatriot Nicolas Almagro, who took Nadal's place at the Abu Dhabi exhibition tournament where he had been due to make his comeback this week. "He doesn't want to play in Melbourne, it's five sets, his knee's not really good, he's not ready for that."
Others have hinted at a growing despondency with an injury which meant he missed the Olympics - where he was defending champion and had been due to carry his country's flag at the opening ceremony - as well as the US Open and Davis Cup final.
"In August, he looked spent," El Pais newspaper quoted a source close to Nadal's entourage as saying. "He had been playing through pain, his head said enough."
World No 4 Nadal has spent much of his career battling tendinitis in both knees, a by-product of his all-action style.
The warning signs were there in 2008, and in 2009 his 31-match winning streak on the clay courts of Roland Garros was ended.
He then pulled out of Queen's and tearfully announced he wouldn't play Wimbledon where he was defending champion, as he needed to cure the tendinitis which had now developed in both knees.
In all, he was off tour for nine weeks and lost the world No1 spot to Roger Federer. It's been a roller-coaster ever since.
At the 2010 Australian Open, he had to quit his quarter-final against Andy Murray with a right knee injury and was out of action for two months.
This year, despite winning a record seventh French Open, Nadal had already been forced to hand Murray a walkover in their scheduled Miami Masters semi-final - this time it was his left knee.
In 777 matches, it was only the second time he had been forced to give an opponent a free pass.
Nadal, who had been due to play his first official tournament in Qatar from next Monday, insisted his knee was improving.
"My knee is much better and the rehabilitation process has gone well, but this virus didn't allow me to practise this week and therefore I am sorry to announce that I will not play in Doha and the Australian Open," he said.
Nadal will see his ranking slip out of the top five as a result of his absence from the tour. It will be the first time that he has fallen so low since 2005.
His decision not to play the Australian Open, where he was champion in 2009, surprised Djokovic, the current world No 1.
"I got in touch with him a week ago and he was saying he was coming here, and that we were going to practise and he said he was feeling better," the Serb said in Abu Dhabi.
"I won the Australian Open last year and I had only played this tournament in Abu Dhabi.
"Obviously for his situation right now that is quite specific, you can't compare it to any other player because he's been off the tour for six months, so I'm sure he lacks matches and confidence.
"I wish him a fast recovery because he is someone that brings a lot to tennis with his success, his athleticism, his competitiveness. It's not good news definitely."
