Yeah but they played in weakest group so far and now they will be cannon fodder. What Latvia just proved. Ukraine has no chance vs Serbia or Lithuania. Same with Belgium. That group is kind of set already.
Second group is way more difficult to predict. For Greece to go through they need to beat Slovenia and Croatia and hope for some help as if Finland wins at least one game they will have tiebreaker vs Greece. Of course Finland can lose all their 3 games. I think for them deciding game is vs Croatia, if they win they will be in as crazy as it sounds.
Greece can beat any team in this tourney. When they bring it they play really good. But it's a fact they made it difficult in the previous round. Let's see.
