Kolkata: Atletico de Kolkata played out a goal-less draw against Chennaiyin FC in a high-intensity Indian Super League fixture to maintain their top spot here today.

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.
