This is the kind of game that Norway should definitely win. They have more experience in the tournament, play better as a team, and have more skill overall. It's exactly why this game scares me the most out of any of Norway's final three.
In past tournaments Norway has made a habit out of stepping up and playing great against good teams and faltering and playing terribly against sub-par teams. Afghanistan falls into this exact category. From what I've seen they've got some decent players and they try really hard - they just don't have the reps quite yet to play with the big boys.
For Norway to win this game its going to have to come out guns blazing in the first ten minutes and set a tone of hard, physical soccer - exactly like it did against Jamaica. The last thing Norway wants is a slow-paced game with hardly any shots because then the chances of it being close are much, much greater. Norway needs to shoot at every opportunity early on and hopefully get up 2 or 3 to nothing. If they don't then watch out because Afghanistan will almost certainly gain momentum the longer the game stays within reach.
If Norway can control the tempo and keep it fast then this game should be over by halftime. Afghanistan doesn't have the striking capacity to make a sustained comeback in only 25 minutes and they're likely to give up if they don't think they've got a hope. Norway has to make them feel the game is over by not being lazy getting back in the midfield and by following through on every single tackle - right from the start. If Norway can do that it will be a blowout.
I'm predicting 6-1 for Norway.
