Watched by a starry Bollywood gathering of Bachchan father-son duo and Deepika Padukone, the match had all the ingredients of an eventful contest, including a 11-minute interruption thanks to a familiar power outage at the Vivekananda Yuva Bharati Krirangan.
But a goal eluded both the teams as ATK would consider themselves unlucky after their star striker Fikru Teferra fluffing an easy chance while their marquee player and captain Luis Garcia's shot hit the crosspiece.
Chennaiyin's star Brazilian forward Elano Blumer also had a lacklustre day, missing some easy opportunities while his clinical freekicks too eluded him a goal.
Both teams refused to play second fiddle in the top of the table clash but it was ATK who had the best opportunity with Fikru firing it wide of the post.
