I'm looking forward to the game. Whoever wins gets to play vs Japan in the next round, but a win against japan means they could face Brazil/Mexico in the quarterfinals. And whoever loses today will have to play vs Colombia in the RO16, but they could have an "easier" quarterfinals (Sweden/Switzerland).
I guess they will play lightly, both of the team will and actually they should avoid any fouls resulting in Cards to avoid further complications. Anyway, Sweden is not easy as well as you seemed to portray, yeah, maybe not on same level, but they are good. And moreover in this most unpredictable World Cup, I say anything is possible or nothing is impossible.
