Both sides got off to an exciting start and strikers at both ends were on an attacking spree but failed to score the all important goal.
The home team's Nigerian striker Penn Orji almost scored in the opening minute but missed it by a few inches. Within 10 minutes, Mumbai's Eric Brown returned an attack that also went wide.
Upping their ante, Lajong nearly scored again in the 22nd minute when their Brazilian recruit Uilliams Bomfin's shot narrowly missed the target.
Resuming after the break, Lajong continued with their raids at the Mumbai goal but failed to convert the chances that came their way.
Mumbai players, it appeared, were affected by the cold weather conditions and the high altitude of Shillong.
