Abstract

Defensive tactics in football are a combination of individual and collective efforts aimed at preventing the opponent's attack, protecting the goal, and regaining ball control. The effectiveness of defense depends on the players' ability to coordinate, judge situations, and apply techniques. The purpose of the research is to identify the criteria and sequences of observed behaviors applying techniques in defense of the U21 football team of An Giang province, Vietnam. The research employs methods of document synthesis and analysis, interviews, pedagogical observation, and statistical mathematics. The subjects observed were 19 matches of the U21 football team of An Giang province, Vietnam, and 30 male athletes from the U21 football team of An Giang province, Vietnam.
