"Katrina has done a lot of hard work for the song. She has given all the power and dedication that was needed. Only Katrina Kaif could have been 'Chikni Chameli', nobody else and she has proved it also," said Acharya.
"We choreographers only choreograph the song, but it is the artist who makes all the difference. She did it very nicely," he added.
Acharya is known for choreographing item numbers like "Beedi" in "Omkara" and "Shalu ke thumke" in "Bin Bulaye Baraati".
The song, composed by national award-winning duo Ajay-Atul and sung by Shreya Ghoshal, has become the USP of Karan Johar's "Agneepath", a remake of Amitabh Bachchan-starrer 1990 movie of the same name. It has garnered over five million views on Youtube.
"Public has given us a lot of love and appreciation. We gave our best... I did all that I could do from my end. I would like to thank everybody for all the love," he added.
The action-drama, slated for a Jan 26 release, features Hrithik Roshan as Vijay Dinanath Chauhan, originally played by Amitabh. Priyanka Chopra, Sanjay Dutt and Rishi Kapoor will also be seen in key roles in the movie.
