Bangladesh toured UAE to play two T20 matches. Bangladesh is stronger than UAE. Currently, UAE is not performing well, UAE has performed very poorly in the last few ODI matches. However, Bangladesh is far ahead in the head-to-head record between these two teams, Bangladesh has won 3 of the last 3 head-to-head matches between these two teams. So Bangladesh is far ahead based on past and present performance, so I think today's match can be one sided.
The real test for the Bangladesh team will be in the tour to Pakistan, which will happen after this short tour to United Arab Emirates. I do not know why they keep only two matches for this series. There should be at least three matches in the T20 series as per the standard, but anyway, I don't think there would be any interest in watching these matches even by the locals there in the UAE. Considering both teams' strengths, Bangladesh should win these matches comfortably and try to use them as a match practice for the upcoming series against Pakistan.
