ATK Mohun Bagan qualified for the knockout stages of the AFC Cup following a 1-1 draw with Bangladesh champions Bashundhara Kings in their final Group D match in Male on Tuesday.
The Indian club made the inter-zonal semi-final of the second tier continental tournament as South Asian Zone champions.
Brazilian midfielder Jonathan Fernandes (28') put the Bangladeshi side ahead in the first half before team-mate Sushanto Tripura (45+2') was sent off at the stroke of half-time.
The Kings were reduced to 10 men in the first half stoppage time when right-winger Tripura was shown a red card.
Needed a win or a draw to go through, Bagan struggled at the start against the pressing game of a determined Kings side and the latter gained control of the match when Fernandes struck one from the edge of the box giving the rival goalkeeper Amrinder Singh no chance.
Both teams had a few chances in the first quarter.
Searching an equaliser in their quest to avoid elimination, Bagan found one after the change of ends when the Kings appeared to be on the defensive with a man down.
