Bangladesh face a tough equation in the U-19 World Cup. Mahfuzur Rahman Rabbis have to win against Pakistan tomorrow to go to the semi-finals. The match of Super Six should not only be won, it should be won by a big margin. How big a gap? The ICC has written on its website about this, "Bangladesh will reach the last four if they can beat Pakistan and overtake them in run-rate." Bangladesh will not reach the semi-finals if they lose to Pakistan or win by a small margin.
