Fifa President Sepp Blatter says bonus disputes arise because African players do not trust their federations.
Cameroon, Ghana and Nigeria were involved in bonus disputes which distracted them at the World Cup, and Blatter says that is why Fifa decided to step in.
Ghana's government failed to provide the money for the players to be paid in time which resulted in rows.
"Players don't trust their federations and that is why they are fighting. They are professionals they want to play for money," he said.
In line with a decision taken after Nigeria's training boycott, Blatter stressed that Fifa would ask for guarantees before any of its tournaments.
"How can we help them? It is by saying to these federations they must arrange at the beginning of the competition what will happen with the money."
