A few clear themes in the first half between Canada and Bosnia & Herzegovina (BH) today.
The home side is dominating possession with an aggressive 2-4-4 structure. The fullbacks are providing double width and plenty of support through under and overlapping runs. Meanwhile, BH are defending deep in a compact and low 4-4-2 block.
With BH defending so deep, Canada are finding it difficult to penetrate during open play. Their man tactic is to overload the box with players and targeting the far post with crosses. Due to the double width, the fullback or winger can get a cross in.
Set-pieces seem to be another potentially valuable route for chance creation via freekicks, corners, and long throws. Canada have relatively generated better chances from dead-ball situations rather than open play, as far as I can tell.
BH are focusing on defending low and springing on the counter. They don't have too much pace centrally through their strikers. So, the reliance is on hold-up play before accessing the quicker wingers. BH are also relying on set-pieces to generate quality chances. They've got tall and physical players to flood the box. The opening goal came from a corner, too. BH are more threatening from set-pieces due to their superior physical profiles.
I don't see these themes changing much for the rest of the game. Canada are proactively attacking and trying to produce chances but BH have been robust defensively so far. A tough and competitive game.
