Serena thinks her peak is yet to come.

Serena Williams thinks her best years may still be ahead of her at the age of 31. She overcame stubborn resistance from defending champion Maria Sharapova in the French Open final on Saturday to clinch her 16th Grand Slam title, beating the Russian 6-4, 6-4 and extending her own winning streak to 31 matches.

‘I want to go out in my peak. That’s my goal. But have I peaked yet?’ Williams said. ‘I definitely want to continue my journey to get a few more.’Williams has some way to go before retiring, then, and a long way to go to match Australian Margaret

Court’s 24 major titles. But she will catch Martina Navratilova and Chris Evert by the end of the year if she wins Wimbledon and the US Open. That would then leave Helen Wills Moody (19), Steffi Graf (22) and Court - who may just be a little too far off to catch.

‘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,’ Williams said. ‘The day I feel that I cannot improve, it’s going to be a problem for me. I’m going to have to debate whether I should keep playing. But I feel like as of know I can do a lot of things better.’ Williams has a bit of extra motivation for Wimbledon. A win there would move her level for major titles with men’s record holder Roger Federer.
