Orchestration
Fixed football matches are generally orchestrated by a network of players, coaches, referees, officials, and other individuals who all share an interest in the outcome of the game being modified.
Collaboration…
At this point, some players can perform poorly or deliberately concede goals, referees awarding dubious penalties or disallowing legitimate goals, or officials ignoring fouls or cautioning players which should be sent off.
Reward!
Finally, results are bet on and large profits can be reaped for the the people involved in these kind of activities.
