The UAE team is very new. On the other hand, the Bangladesh team has been associated with cricket for a long time. Although I am very upset by the performance of the Bangladesh players. Even then, winning against the UAE is not a big task for Bangladesh. Bangladesh should get an easy win. But Bangladesh is a team whose performance is impossible to predict.
Only 2 T20 matches will be held in this tour. Bangladesh captain Liton. However, experienced players like Mushfiqur and Mahmudullah are not in the squad. Senior players like Shanto, Liton, Mehedi, Soumyo and Mustafiz are in the squad. However, the performance of each player of the Bangladesh team is quite irregular.
Bangladesh may win against the UAE since the UAE is not in good form. However, I doubt whether Bangladesh will be able to dominate and win. Bangladesh should win by a big margin against a team like the UAE.
UAE is not new to international cricket, as far as I remember they were in 1996 ODI world cup. The issue with UAE and other gulf team is that they don't have native players in the squad. The whole UAE team is composed of players from sub-continent and there is no supply of local players from there domestic setup. That's why their performance is not improving despite spending so many years in international cricket. Bangladesh players right now are engaged in IPL and PSL so they can go with there young players in this 2 T20I series.
