Before the tournament start Sweden could have been said to be able to play this game without pressure, but as it stands now Sweden should have at least just as good chance to win as Russia. Both teams will be dissapointed with a loss ( well "duh", but I hope you get my point).
If we would compare Switzerland to Sweden, which team would fit the Russian the best? Sweden has better depth at forward and perhaps also better top end forwards than the Swiss, but the Swiss might just have a better teamplay/better suited for defensive play.
Sweden showed great promise against Finland with their offense but their deffense will still need a lot of improvement. If russia continues to play like they did today this should not be to much of a problem.
Only negative thing about this swedish team is that their penalty kill is abysmal, the shots gets through from the point 9 times out of 10 etc. Goaltending is also a questionmark. Lassi is a dwarf, Lundström we just don't know where we have him. Vasilevsky is saftey personafide, so big, so athletic... great in shootouts as well.
Tricky to guess, however since I am not objective I'll guess Sweden 4-2 in regulation time. However I fear we will see better play from the russians - they certainly can and they should be properly motivated by now.
