This match turned irrevocably on two red cards. At 2-0 and eleven men, the game was already drifting away from Alfaro's Qatar; at 3-0 and nine men, the question became only how large the margin would reach. David's proficiency in front of goal — which had looked uncertain in the Bosnia draw — returned in full, with three finishes that were clean, well-placed, and composed. Canada's movement in the final third ruthlessly exploited the spaces that increasingly desperate Qatari positioning left open, and the 6-0 is a scoreline shaped as much by Qatar's self-destruction as by Canadian brilliance; but the points are real, the group table is honest, and Canada are top with a goal difference that would have seemed impossible forty-eight hours ago.
