They've looked rough leading into the tournament but I think they can beat Senegal, at least. Poland...maybe a draw.
Colombia is going to struggle. They did not look great.
I don't think Japan will advance, either, I just think it is very possible.
Russia has been steamrolling people early - not all that surprising, but what is surprising is whether or not they win or take runner-up in Group A, they are highly likely to face either Spain or Portugal as their first opponent in the knockout stage. I figure they would have been "given" a better draw than that.
Heartbreaker. Iran played well enough to draw.
