Madrid: Rafael Nadal says his game this year has been too predictable and he has sometimes lacked drive on court -- weaknesses he plans to overcome for Wimbledon and the 2012 Olympics.
"With the years, you lose a bit of intensity. Intensity in your self-belief, concentration, being positive, believing things will go well -- those are in the mind. With the years you lose that a bit," he told the Spanish daily El Pais in an interview published Monday.
The 25-year-old world number two led Spain to a fifth Davis Cup title in December and won the French Open this year.
