The main problem of the Bangladesh team is the irregular batting of the batsmen. We will not find a batsman in the squad who is capable of batting responsibly and playing big innings. The batting of every batsman in the squad is irregular. Also, I would say that the Bangladesh team management should consider the condition of the pitch and form the squad. I do not find any reason to keep 4 pace bowlers on a spin-friendly pitch.
If we talk about the management of Bangladesh, we can say that the management is filled with incompetent people, and there is no discussion, criticism, or research on what kind of players to keep in the squad. Today's T20 match had a pitch that was completely conducive to spinner wickets, but the squad was made up of three pacers: Taskin Ahmed, Mohammad Saifuddin, and Tanzim Hasan Shakib. Taskin Ahmed was the most expensive bowler in the match. I will never blame Bangladesh's bowlers because they bowl exceptionally well, but the failure of the top-order batsmen and slow batting were one of the main reasons for Bangladesh's defeat.
