Serbia can be beaten, of course we have a bad history with Yugoslavia but as you can see it's only Serbia * getting smaller and smaller * and Croatia si way better then them.
I'm more afraid of a 0-0/any tie after we lead 1-0, 2-0 rather then a loss.
You can never know what to expect from this team, as long as Piturca is there, I mean you play Holland at a Euro when they are 1st place guaranteed, they play like in a training match and you mostly defend, with Lithuania you treat them from up high then you lead a wasted France 2-0 only to give them space.
More afraid of the game v. Austria in Klagenfurt, if anybody would have investigated, Romania doesn't have a Wednesday match at home ( and even away i think ) that comes after a free Saturday? Austria has this advantage playing at home after Romania has a important game with Serbia a few days before.
I'm pessimistic about the qualification, though I was pretty sure before the first match that, except for the thing Austria came from a weak slot, this group can be won and no points to be lost except with France and Serbia Away.
