Sweden - Ukraine. It something incredible that Ukraine who qualified from 3rd place got their own level opponents, while Austria from 2nd place had to play against Italy. I'm backing Ukraine in this game.
England have been to highly favoured from the start and don't deserve their 4th placed world ranking. Germany are 12th for example. Both teams were inconsistent though. Germany demolished Portugal but drew with Hungary and lost to France. England have been mediocre despite not losing. I think I'd still slightly favour Germany but I could see this game being a draw and maybe even going to penalties. I'm hoping for a high scoring game either way. If England can make it past them then it shouldn't be too difficult to get into the final from there.
