MADRID - Champion Rafael Nadal will do all he can to fix problems with his knees and be fit to defend his Wimbledon title this month, he said yesterday after tests at a clinic in Barcelona.

The world number one was forced out of this week's traditional Wimbledon warm-up tournament at Queen's Club with tendinitis and said he faced two tough weeks of recuperation before Wimbledon gets under way on June 22.

"I will give 200percent to be at 100percent for the most important date in world tennis and the tournament that has always excited me the most," the Spaniard said.

"I have been playing with pain in my knees for several months and cannot continue like this."

After his shock defeat to Robin Soderling at the French Open nine days ago, Nadal said he had been advised to rest by doctors and pulled out of Queen's in London, where he was also defending champion. - Reuters
