India's Saina Nehwal on Tuesday lashed out at Badminton World Federation for denying the athletes, among other things, access to trainers and physios ahead of the upcoming tournaments in Thailand and urged BWF to address the issues at the earliest.

In a series of tweets, Olympic bronze-medallist Saina expressed her displeasure at the restrictions imposed by BWF as part of its COVID-19 protocols for the bio-security bubble. "The physios and trainers cannot meet us during the entire tour after all (al) of us have tested negative? @bwfmedia @bwf_ac. 4 weeks of this how is it possible to maintain ourselves. We want to play the tournament in good condition.
