Former US. Open champion Coco Gauff has revealed that she is ready to improve on her area of weakness after changing her coach following a feeble defence of her title.
Gauff won her first Grand Slam title at the U.S. Open last year under Brad Gilbert, but she announced that she had sacked the coach after her poor performances at the U.S. Open, where she lost to Emma Navarro in the fourth round, producing 19 double faults.
