Coach's Complaints About Football, "Scientific Facts"

Blog Article

Mikel Arteta (Arnall) and Pep Guardiola (Manchester City) criticized the official ball used in the English Football Association (FA) Cup and the Carabao Cup in the 2024-25 season, respectively. After the Carabao Cup match, Arteta complained that "the ball flies and the grip is different from that of the Premier League," while Guardiola directly pointed out the quality of the FA Cup match, saying, "It is difficult for the ball to control." The Athletic concluded on the 9th that "the Loughborough University Sports and Technology Research Institute in England partially confirmed the validity of the claim through scientific analysis," and that "the coaches' complaints were scientific."

The Loughborough research team conducted player experiments and robot tests on three official stadiums (Puma Carabao Cup, Meiter FA Cup, and Nike Premier League balls). The players felt differences in the amount of rotation and the sense of hitting on different balls, and there was also a slight difference in the actual flight trajectory. Differences in speed, rotation, and firing angle were detected for each ball. It was concluded that the Meiter ball rotated more than the Puma and Nike balls. However, in the robot test, there was no significant difference in kicking all three balls at the same speed and angle within FIFA standards, and the physical characteristics were analyzed to be uniform. In other words, the conclusion is that there is no significant mechanical difference, but humans can feel differences in psychological and physical senses. 먹튀검증
Soccer balls are manufactured differently with technology. The number of panels on the ball, the surface structure, and the bonding method are all different. Nike has four panels, Meiter has four panels, and Puma has eight panels. This difference will affect flight trajectory, air resistance, and the size of the sweet spot. "The feeling of the ball may vary depending on the individual players' physical conditions and sensory differences," experts said. "The coaches' arguments are not just excuses, but differences that can be felt in real life."
