We lose whenever Nazimuddin's not in the side. Just look at our overall win-loss record in all 3 formats and then see just how many of those Bangladesh teams had Nazimuddin in them. I bet over 99% of losses were with teams without Mohammad Kohlimuddin Amla, the tragic hero of BD cricket. Then look at our wins with teams with the man playing. I bet you'll come upon a much higher percentage.
If we lose when happens to be in the side, it's always someone else's fault.
"O people, we created you from the same male and female, and rendered you distinct peoples and tribes, that you may recognize one another. The best among you in the sight of GOD is the most righteous. GOD is Omniscient, Cognizant." (49:13)
