PARIS—Rafa Nadal understands it will be a “big challenge” for him to beat Novak Djokovic in Tuesday’s French Open quarter-final but the 13-times winner vowed not to shy away from a fight against the world number one.
Nadal had won the French Open four years in a row before losing to eventual champion Djokovic in the semifinals last year—just the third time he had been beaten at the claycourt major since his debut in 2005.
