Mbappé, chaos and losses

The situation changed radically in the second half. Mbappé's introduction added threat to the space and his ability to hold the ball high, forcing Barça to run backward. This opened up the game and caused Barça to lose precision in their pressing after losing the ball. This, along with the introduction of midfielders with better footwork (especially Modric), allowed Madrid to string together the two or three passes needed to break the pressure and launch counterattacks. Furthermore, Barça lost possession five times, leading to the foul and corner kick that led to Real Madrid's goals.
