Paulo Josue (59') gave the visitors the lead on the hour mark much against the run of play before Mohammad Fardin Ali Molla (90') equalised for ATK Mohun Bagan in the dying minutes of regulation time.
The Sydney-born, 29-year-old defender started his career by playing in youth academies and lower division clubs in Australia and made his professional debut at Melbourne Heart FC (now rebranded as Melbourne City FC) in 2010.
