LONDON — Thomas Vermaelen’s header hit the ground first and then rose before colliding with the post near the corner where it meets the crossbar. As the ball spun out, sideways toward the middle of the goal, Lukas Hradecky, the Finland goalkeeper, was still turning around. It was all happening in the blink of an eye. Instinctively, Hradecky reached out a hand to try to swat the ball away. In that instant, on his fingertips, a substantial portion of Euro 2020 hung.
Had Hradecky been able to claw the ball away from his goal, away from danger, Finland might have been able to hang on, to keep a vaguely interested Belgium at bay, to qualify for the knockout stages of the first major tournament it has ever reached.
