You might have missed it as the camera angle was panned down to a close-up on the corner flag in the 79th minute. With Liverpool 3-0 ahead against Barcelona in their Champions League semifinal second leg but tied 3-3 on aggregate, the announcers were taking a breath ahead of what seemed like a run-of-the-mill corner kick and even Anfield itself seemed quiet.
An extra ball rolled over to a scampering ball-boy; Xherdan Shaqiri shuffled toward the corner flag and Trent Alexander-Arnold measured his steps away from the ball. Then, while the Barcelona players were still setting up their marking assignments, Alexander-Arnold suddenly cut his set-up short, scampered back to the ball and bent in a low cross along the ground to Divock Origi, who was standing unmarked in the six-yard box.
