Nadal lost to Felix Auger-Aliassime at the ATP Finals in Turin to extend his losing streak to four matches.
The defeat followed losses to Frances Tiafoe at the US Open, Tommy Paul at the Paris Masters, and Taylor Fritz in his first round robin stage match in Turin.
“I don’t think I forgot how to play tennis, how to be strong enough mentally,” Nadal said after the match. “I just need to recover all these positive feelings and all this confidence and all this strong mentality that I need to be at the level that I want to be.
