Rafael Nadal claims his improved serve gave him the boost to go on with the successful season he had. Nadal had one of the best seasons of his career in 2019, winning his 12th French Open, US Open, the Davis Cup and also ending the year as world No.1. 2020 could be a seismic year in tennis as Nadal is one Grand Slam behind Federer in the all-time list. He insists there won’t be any regret if he can’t surpass Federer.
