WINNER: Serena Williams holds her WTA Championship trophy in Istanbul (PA)
SERENA WILLIAMS coach Patrick Mouratoglou has said 2014 will bring even more success for the world number one tennis star who has enjoyed an incredible year.
Yesterday (October 27) the American defended her WTA Championship in Istanbul, claiming her 11th title of the season – her 78th win of 2013, while having only lost four times.
Mouratoglou, widely credited with helping Williams dominated across the courts, told BBC Sport: “We've spoken about 2014 already with goals to do better than this year because I think it is possible.
“If we keep this mentality I don't see any reason why she would slow down.”
This year has been a record-breaking one for the 32-year-old Williams, who has become the first woman to earn the most prize money in a single season – she has won over $10m (£6.19m).
Her coach added: “She loves playing tennis, she loves winning, she wants to stay number one, she wants to keep on winning - and she wants to be better.
“She has 100 per cent of her physical abilities today, which counts for a lot.
“Maybe that's one of the reasons why Roger [Federer] hasn't been able to play his best tennis this year. He has physical issues, but Serena doesn't. She's at the top physically.
“As I said to her when we started working together, we have to make sure you don't get injured: that is the first goal. So we did a lot of work on her body.
“The team worked with her to help her get stronger because everybody has weaknesses in his or her body. Her fitness is at the top, along with her will and dedication.”
