After watching the Canada-game, all I can say is, that I´m very excited that we have a player like Barkov in Finland. The overall package that he brings at such a young age is pretty remarkable.
I followed him pretty closely and below you can find some good moments and one bad moment from yesterdays game

Here is the link to the game:

20:20, Nice move with the puck, but is forced to dump the puck after that.
23:30, manages to get a shot off from backhand, but couldnt capitalize the opportunity. Great save from the goalie.
36:24 a nice challenge on d-man, that leads to a good scoring chance.
38:13, loses a faceoff 0-100, and Canada immediately capitalizes 1 second before the end of the period.
60:57, Sasha marches in to Canada´s zone and a great feed to teammate who did not score.
70:30, Beautiful takeaway from a Canadian player.
70:40, Nice wrister from blueline, very effortless IMO.
105:54, Another nice takeway, where he outpowers the Canadian d-man.
109:18, nice feed to linemate from a difficult position, unluckily a close offside call.
He is still a little rusty with a puck and he did lose some key faceoffs at 3rd period, but other than that he looked very good. Also, he did not play powerplay a whole lot, couple of shifts in 1st period, but he was used on penalty kill.
He did not register a point, was -1, and won 60% of the faceoffs. Points will surely come as the tournament proceeds. Teräväinen´s line is probably playing the powerplays whenever they can, Barkov´s line is the 2nd unit, but they were not used that much.
