Rafael Nadal has said that although Novak Djokovic is currently ranked the best in the world, he believes that the Serb is "always beatable".
The Spaniard has lost out to the world number one in each of the last three Grand Slam finals.
Speaking to Spanish TV network TVE, Nadal said: "[Djokovic] is the best right now, but he's always beatable."
The 25-year-old has not played competitively since losing the Australian Open final to Djokovic last month.
