"Rafa convinced me by practicing with his shirt off," said Azarenka, who on Sunday lost 7-5, 6-7 (6/8), 6-1 to Serena Williams in the women's championship match.
Williams opted not to select a favorite.
"It's tough to say anything against Nadal because he's been doing so well and he's lost like never this year," she joked of a player who's been defeated just three times in 62 matches since February.
"Djokovic, this is his fourth time in the final, and he has a good record against Rafael. It's going to be an interesting match."
