LONDON: Fifa’s technical report on the 2026 World Cup has highlighted an increased number of tactical strategies at the tournament but concluded that there was not necessarily a "winning formula".

A 500-page report on the tournament published on Friday said the key tactical innovations identified included building with a back three, wide player rotations, changing the point of attack, attacking transitions, a structured high press, defensive blocks and counter-pressing.

The report offered “unprecedented insights into how the best national teams and players on the planet are reshaping the modern game”, PA Media/dpa reported. All 104 tournament matches were observed using advanced data and video analysis, and 11 “key tactical and technical” trends were identified.
