Yes Parvez Hossain Emon century was amazing to watch. He hit nine sixes and five fours that is kind of batting that makes people excited. You are right even though Bangladesh won it is bit worrying that other batsmen did not score many runs. They can not always depend on just one person to bat really well. For UAE team it is good that Muhammad Waseem scored 50 runs. Even though they did not win this time but there are good signs for their batting. Maybe they could have scored enough runs to win. It is good that they tried hard.
Bangladesh could have given a higher target if batsmen apart from Parvez Hossain Emon have scored runs. If we see scorecard of Bangladesh then it's dominated by Parvez Hossain Emon alone and no other batsmen took responsibility to score runs once Parvez Hossain Emon got out. UAE lost the game but their performance is satisfactory and they must look at mistakes made in this T20I to improve performance in next T20Is. One thing which UAE need to look at is that whole team came to bat but only three batsmen were able to make it to double figures.
However, Bangladesh plays like this, if any one player performs well, the rest of the players cannot provide proper support, but in yesterday's match, the only batsman, Parvez Hasan Emon, scored a brilliant century, which can be said to have played a role in Bangladesh's victory. If we exclude Parvez Hasan Emon's century (107), then it must be said that the United Arab Emirates played better than Bangladesh. If any batsman from the United Arab Emirates could have scored a century like Parvez Hasan Emon, then it can definitely be said that the United Arab Emirates would have won.
