The headline is that Afghanistan absolutely have to win in order to make the Super Four, or else Bangladesh get in ahead of them. Sri Lanka merely have to avoid being handed an all-time thrashing.
If Sri Lanka bat first and make 150, for example, Afghanistan would have to chase that target down in 11.4 overs in order to knock Sri Lanka out and have Bangladesh accompany them to the Super Four. If Afghanistan bat first and make 150, Sri Lanka would have to score 84 or fewer for Bangladesh to qualify.
Essentially, Afghanistan need to win. Bangladesh would ideally like Sri Lanka to win. But if Sri Lanka lose, Bangladesh need them to lose by a gargantuan margin.
