Former World No. 1 Saina Nehwal is going through the toughest phase of her career and needs to take care of herself so as to avoid any more defeats, says former national champion and coach U Vimal Kumar.

Saina, currently ranked 20th in the world, was knocked out of the first round of the ongoing second Thailand Open. She had earlier fallen in the second round of the first Thailand Open, which was also her first tournament since the All England Championships in March 2020.
