At the moment, there is not a single Bangladeshi who is consistent in the batting department. Litton Das used to be consistent, before losing his form a couple of years ago. And the domestic system in Bangladesh is not producing enough younger cricketers to replace those who are already in the squad. One solution would be to ask the A and U-23 squads to tour SENA countries more frequently, but that is also not happening. There is no quick-fix solution here. Bangladesh, I feel is a lost cause.
Pakistan team has won two opening T20I matches of this series but this doesn't mean Pakistan team has become a strong team. Bangladesh team visited Pakistan last August and won both test matches. Both Pakistan and Bangladesh are struggling in international cricket and fix to there current problem lies in improving the domestic infrastructure. For now Pakistan can cheer this T20 series win but there real test will be in ICC events and also in bilateral series against countries like Australia, Newzealand and England.
