I think Ukraine, Sweden, Bosnia and Norway will make it.
I agree with David's picks actually though I'm not totally confident about any of it. I guess Ukraine would be what I am most sure about.
Why Sweden?
It's a coinflip/very very slight advantage Denmark As a fan, you can't help, but root for the storyline of a final Ibrahimovic run after missing out on the World Cup, and I get drawn to the gutsy upset pick. Neither did much in the group stage. Denmark couldn't beat superior teams. Sweden's draw with Austria was the only dent in the Austrian record, yet they also got beat badly too. Whatever though...national teams mean surprisingly little for me. I wouldn't bet on it, but as a fun pick, I'll go Sweden.
