Rafael Nadal must overcome the spectacular shot-making of Stan Wawrinka if he is to win a record 10th French Open title on Sunday.
The Spaniard, 31, will become the first player in the open era to win a Grand Slam title 10 times if he wins.
Swiss third seed Wawrinka hit 87 winners as he beat world number one Andy Murray in the semi-finals.
"It's true that when he hits hard, he hits really hard. Stopping him can be difficult," said Nadal.
"I know he's dangerous when he plays aggressively, so I need to limit his possibilities.
