The crowd inside SoFi Arena collectively gasped at the moment of brilliance from the substitute but Endo wasn't finished.
He drove the ball forward, making a sprinting run through the heart of the midfield.
He looked up and saw Curtis Jones open on the left.
With a sharp pass, Endo fed Jones into space just outside the box. The Liverpool fans around the stadium held their breath as Jones controlled the ball.
He cut inside with pace, looking to get a shot off, but William Saliba was quick to close him down, forcing Jones to take a shot from a tight angle.
But the ball ricocheted off Saliba's boot and found its way to Mohamed Salah near the edge of the 18-yard box.
Salah, ever clinical in these situations, seized the moment.
He fired at goal with venom, but just as the ball was about to strike the net—David Raya launched himself at the ball, diving low to his right.
