The Barcelona players were trapped in a vicious cycle.
It all started with them being unable to control the ball at their feet. They began to feel indignant toward the venue in which they were playing, and, as a result, their internal feeling of agitation began to rise. These erratic emotions led to erratic movement, and they became unable to perform at their best. So, they continued to struggle to control the ball, continued to blame the terrible venue for their mistakes, and continued to feel agitated and enraged…
And the cycle repeated.
Not a single Barcelona player had the right psychological framework for the match. The players responsible for the team's offense were agitated, and the players responsible for the team's defense were on edge.
