A win alone is not sufficient for India to qualify for the semi-finals.
They will have to beat Sri Lanka by a minimum of 20 runs on batting first, and with 2.1 to three overs to spare on batting second, in their last Super Eights clash of the T20 World Cup in St Lucia on Tuesday.
Not only India needs to win big, but also Australia must beat hosts the West Indies in the second match of the day.
If Australia beats the West Indies even by one run, India will be through.
India needs to boost their net run-rate, which is a dismal -1.578.
However, despite losing to Australia by a huge margin of 81 runs, Sri Lanka have a NRR of -0.600, while the West Indies' NRR is -1.057.
India lost its first two Super Eights matches to Australia and West Indies and face ouster from the championship.
