There were rumours that Singh was in consideration for a role in the movie.
But clarifying his stance, he said: "I really wanted to be part of that film, I wanted to work with Aamir Khan. 'Dangal' the title itself is very good and catchy."
Aamir plays a wrestler in the film. Singh is a big fan of Hollywood star Sylvester Stallone and is a trained boxer himself, so he thought the genre of 'Dangal' suited him.
"I had played a tough Haryanvi Jat in 'Heropanti' and have a command over that language. The characters of 'Dangal' also have their backdrop in Haryana. So I thought of giving it a try, and spoke to Aamir sir to see if there is a role of a main villain or something similar," he said.
Casting director Mukesh Chhabra, who is known for bringing the right faces for some of the popular films of the industry, was also involved with "Dangal". So, Singh approached him.
He said: "We were in touch, but there was nothing concrete that they could offer me. Even Aamir sir told me that there is nothing concrete because you have done the successful 'Heropanti' as the main villain and also done lot of quality work in south India.
"So it was not something very meaty or interesting for me. I took Aamir Khan and Mukesh's advice... They guided me that there is nothing which could help my career after doing so many films and having such a zeal to grow. So I dropped the idea of 'Dangal'. But people still think that I'm a part of 'Dangal', we can't do much about it."
Singh was last seen as a villain in Kannada film 'Rana Vikrama', for which he dubbed his own lines.
