Saina today announced the decision on her twitter handle.
"For a while I've been thinking about moving my training base back to the Gopichand academy and I had a discussion about this with Gopi sir and I am really thankful to him for agreeing to help me again," Saina tweeted.
"At this stage in my career I think he can help me achieve my goals," she added.
The 27-year-old champion shuttler had split with the national coach Gopichand before the 2014 Asian Games at Incheon, deciding to hone her skills under Vimal Kumar in Bangalore.
