"It got really complicated today," Williams said. "I was getting a little bit nervous, and Lucie was just playing great. She was a magificent opponent. She was playing very aggressive and she had no fear.
"To win my 20th Grand Slam title at Roland Garros is very special for me because I haven't always had the most success here. I want to thank all of the fans - it's just a dream that I've won this title."
