American tennis player Serena Williams believes her father Richard deserves the lion's share of credit for the most dominant phase of her career she is enjoying, having lost only five matches since the French Open last year.
According to The Scotsman, it was following her shock first-round loss to Virginie Razzano in Paris that Williams began working with Patrick Mouratoglou, and the French coach has received a lot of praise for the impact he has had.
However, Williams has expressed that the partnership only works because Mouratoglou has backed up the advice of her father, who is still a key figure in her tennis, the report said.
Serena said that her father was very innovative and had built the foundation for her and her sister's game.
She said that he had written some advice to her recently and she thought that it was exactly what she needed to do, adding that her father was a great coach.
Williams has certainly been the most impressive player so far as she bids to defend her US Open title, the report added.
