The immaturity of the team was often reflected in two aspects: one was the lack of maturity in the tactical system, meaning the team's offense and defense were chaotic; the other was the team's mentality, which lacked stability and composure in crucial games.
Today, Manchester City exhibited both issues.
It was the immaturity of their mentality that led to the collapse of their tactical system.
The team had trained in cooperative passing and movement, focusing on quick, efficient one-touch football. Nevertheless, while striving for a fast tempo, they also had to consider their ability to cope with that speed.
For instance, if a pass was too long, players couldn't catch up; if a pass was too early, players weren't in position. This directly correlated with the maturity of a team.
