This paper studied the defensive tactics of eight top teams in 48 qualifying matches leading of the 15th World Cup football game in 1994. This study was conducted by repeated actual visual observation of the defensive skills demonstrated in the matches. The findings of the study were as follows: I. The ability to mark and tackle opponents was essential to strengthen the overall defensive performance of a team. Individual players’ defensive skills contributed to the defensive tactics of the whole team. Besides, area defense combined with marking opponents was a tactic which will continue to be adopted. 2. Teams of varying performance skills adopted different defensive tactics; defensive tactics of counter-offensive and in vying for center forward position had been greatly improved. 3. The re-appearance of the Brazilian formation of two halfbacks had caught the attention of other teams, while the formation of free halfbacks needed improving. 4. Tackling tactics against top opponent players and counter offensive skills had yet to be strengthened. 5. Training in defensive tactics and strategies had to take into consideration changes in the rules of the sport; stricter enforcement of the rules by referees governing sliding tackle from behind, fouling from behind and showing of red and yellow cards were worthy of note.
