Indian club East Bengal produced an utterly dominant show to crush Bangladesh's Bashundhara Kings 4-0 in their AFC Challenge League match on Tuesday.

Struggling at the bottom of the 13-team table in the Indian Super League, East Bengal looked a far cry on the day in the continental tournament, opening the scoring as early as the first minute through Dimitrios Diamantakos' left-footed shot from the centre of the box off a Lal Chungnunga cross.
