It was Lajong who had the upper hand in both the halves with some dominating football but failed to find the back of the net.
Lajong made two changes in their starting line-up as Alen Deory replaced captain Samuel Lalmuanpuia and Kenstar Kharsong was handed his I-League debut in place of experienced defender Juho Oh.
It was the home side who were dominating straight from the kick-off as they enjoyed most of the ball possession.
Ivory Coast striker Abdoulaye Koffi had the first chance of the game in the third minute mark when Alen's through ball fell at his feet and he launched his shot, but the ball went straight into the hands of the Chennai City keeper.

The inclusion of Alen seemed to be the right move for the Reds as the striker was finding the majority of the ball on the right flank and was allowed to make his blistering runs.
The hosts were enjoying the majority of the possession in the attacking half and were creating chances from set pieces but none of the efforts were threatening enough.
Hardy soon went for a long ranger on his own but the ball fell straight into the keeper's hands. Lajong had some follow up corners, but the Chennai defence was strong enough to clear out the danger.
Lajong started the second half right where they left off. Substitute Samuel Lalmuanpuia shot one from distance but his shot went over the post without creating any trouble for the Chennai keeper.
Koffi then dribbled past three Chennai defenders but failed to keep his shot on target.
Chennai too had a few opportunities in the hosts' box but they didn't manage to test Lajong's keeper Phurba who rarely had to make a save.
In the 78th minute Lajong had their best chance of the half. Aiman's cross from the left was intended for Koffi, but the forward failed to connect and the goalkeeper had to come up with a brilliant save to keep Lajong off scoring.
The hosts went on an attacking spree looking for a goal in the dying minutes of the game but all their attacks were cleared away by the visitors.
In the second minute of four additional minutes Lajong had their last chance to secure three points at home. Samuel Lalmuanpuia's perfect freekick from thirty yards fell straight into the heads of Koffi, but the striker's header went wide of the post.
Lajong will now host AIFF developmental side Indian Arrows January 8 here.
