New Delhi: Struggling with her form, India's top shuttler Saina Nehwal has split with National coach Pullela Gopichand and sought the help of former chief coach Vimal Kumar to prepare for the prestigious Asian Games in Incheon, South Korea.

Saina had broken her 20-month long Super Series title draught, winning the Australian Open in June and also performed well at the Uber Cup in May but fitness issues forced her to withdraw from her title defence of Commonwealth Games in Glasgow.
