This game can only have a good effect on Switzerland.
Either they loose with a great goal difference and are provoked into a reaction so they play better in the next round,
Or they loose after a tight match and see what they can play better than in the two previous matches,
Or they go into overtime, and OT win being more a thing of luck than anything else and so they can say they were Sweden's equal; again something for the confidence,
Or they actually win, which will be a great boost for the self-confidence, especially as it would be the first time in a while that SUI wins against SWE.
