Mohun Bagan had beaten the same opposition 3-2 in the first leg in Guwahati but they have come here without registering a win in three matches in the I-League which saw their title chances going up in smoke.
After the Guwahati match on March 16, the defending I-League champions have lost to arch-rivals East Bengal in the Kolkata derby played in Siliguri and then drawn against Shillong Lajong and DSK Shivajians.
Mohun Bagan are at the top of Group G with nine points after winning all the three matches they have played so far. Yangon and Maziya Sports & Recreation of Maldives are on four points each.
A win tomorrow will consolidate Mohun Bagan's position at the top of the group and seal a knockout berth in the continental tournament. They will, however, be without influential Haitian playmaker Sony Norde who aggravated his knee injury during the I-League match against DSK Shivajians.
