It is a very good suggestion, but as Orpheus says, does not count for Bangladesh.
When in case of other teams, home support is one of the major advantages for the home team, in case of Bangladesh, it turns out to be opposite. Why? I don't know - I would prefer to call it a reverse technique or reverse psychology something.
So you see, it is always in away matches that Bangladesh can win. Bangladesh may perform better against stronger oppositions at home, but for some reason, Bangladesh have never ever managed to beat a team in close situations at home.
