RIO DE JANEIRO (AP) FIFA wants proof from future World Cup teams that players are paid on time after a dispute involving Ghana was resolved by cash shipment.
FIFA secretary general Jerome Valcke says action is needed after Ghana players threatened not to play Portugal on Thursday until money arrived from Africa.
Valcke says ''it's sad that we end up with such a story where they were talking in some way about a strike.''
The FIFA official says ''the fact that the money came in cash is also sad.''
It was the second pay dispute involving an African team.
Cameroon arrived one day late in Brazil after players refused to travel until bonuses were agreed.
Valcke says ''we will make sure'' that participating national associations show written agreements of paying players by bank transfer.
