Serena Williams completed a year of domination by winning the 2013 French Open - and then declared her best is still to come.
The 31-year-old defeated last year's champion Maria Sharapova 6-4 6-4 to win her second title at Roland Garros 11 years after her first.
Williams has now won 31 straight matches and 74 from 77 in singles since her shock loss in the first round here last year against Virginie Razzano, a run that has brought her three grand slam titles and an Olympic gold medal.
She is the oldest French Open women's champion in the Open era, but at an age where many tennis players have called it a day, Williams is playing better than ever.
She said: "I definitely want to go out at my peak. That's my goal. But have I peaked yet? I'm really relaxed. I really enjoy every moment that I'm out there. I always said that I felt like I have never played my best tennis.
"I have said that for years, that I feel like I can always do better and play better and I have always wanted to reach that level. Maybe I'm just trying to get there.
"I really believe age is a number at this point, because I have never felt so fit. I feel great. I look great."
This year's run at Roland Garros, where she has dropped only one set and looked the champion elect throughout, could not have been a greater contrast from 12 months ago, when she left the grounds distraught at her early exit.
She has certainly responded in the right way, though, and she said: "I'm still a little bit upset about that loss last year, but it's all about how you recover.
"I think I've always said a champion isn't about how much they win but it's about how they recover from their downs, whether it's an injury or whether it's a loss."
Sharapova put up a sterling defence of her title, coming out firing, and she could have been 3-0 up but let a 40-15 lead slip on her own serve.
Williams reeled off four games in a row and, although Sharapova levelled at 4-4, she dropped serve again immediately and with that went the set.
The pair were trading huge groundstrokes from the back of the court and playing at a very high level, but it was always Williams who had the edge.
She broke again in the third game of the second set and Sharapova could not get anywhere near the phenomenal Williams serve, with the world number one clinching victory with her third ace of the final game.
"At that point I was just so nervous," said Williams. "I thought, 'I'm not going to be able to hit groundstrokes.' No joke.
"And as you see, the one ground stroke I did hit went like 100 feet out. I thought to myself, 'Look, Serena, you've just got to hit aces. That's your only choice.'"
Williams has now beaten Sharapova 13 times in a row, a run that dates back to 2004, but she felt today was the best the Russian has played against her.
Sharapova put Williams' incredible form down to using her considerable weapons on a more consistent basis, with her serve an obvious advantage over the rest of the women's tour.
The American served 41 aces in the tournament, with Sharapova next at 24, and she also sent down the fastest serve at 124mph.
The Russian felt she had played well but rued not taking her chances in the third game and then dropping her serve at 4-4.
She said: "I know I'm nitpicking here, but these are moments against her that I feel that I should be able to take, because then she has no pressure going in and serving and being up a break at 5-4, and serving harder than David Ferrer when he gets to the final of Roland Garros.
"We know she's going to be able to hit a big serve. I think if I was built like Serena I hope I'd be able to hit a big serve like that, too."
Having seen her title wrested from her, Sharapova vowed to use it as motivation, saying: "You lost and you can be really down about it, and I am because I'm a competitor and I'm a fighter and I don't train to lose. Nobody does.
"But that's the feeling that ultimately will make you work harder and make you think a little bit. It gives you more determination. So I hope that that's what I take away from the match."
The win took Williams to 16 grand slam singles titles, sixth on the all-time list, two behind Chris Evert and Martina Navratilova.
"Today when I won I was trying to win the French Open, I wasn't trying to get to number 16," she added.
"I think it's really special. I feel like I definitely want to continue my journey."
