If you are familiar with Bangladesh Cricket, you should not be this much confident. You never know if Bangladesh is going to be all out for 50 runs against australia if they batting first. You never know if Australia going to score 400 and Bangladesh may score less than hundred losing all wickets. If something like this happen in the next match, Sri Lanka is going to play the champions trophy and Bangladesh will have to watch it. As a Bangladeshi, I am pretty much worried about next match. Australian hero of the previous match is not going to play against Bangladesh. Still, I am not that much confident as like you
