I have been saying for a WHILE that Namibia has a very strong team for US or any other ICC associate sides. They are probably not going to trouble the big teams but they can beat us or teams like Kenya/Canada on any given day.
5-0 is too much, it's just a negative attitude. 3-2 is possible but I'd go for a 3-2 or 4-1 for Bangladesh. Even if we lose, so what ? It's not the end of the world. Yes, the papers will bury the team, the 'seasonal fans' will lose interest but it won't matter once we post a couple of wins in the world cup.
OUr win against Kenya and Canada are just dreams/hopes, there is no assurance that we will win those two matches.
