UEFA's Financial Fair Play will be reformed and altered on many topics. But, there was no agreement found on a salary cap parameter.
Now, the FFP will be based on revenues and costs. The teams who are part of UEFA competitions cannot exceed their expenses more than 70% of revenue.
"Clubs will be able to spend up to 90 percent of their revenues before that figure will be brought to its permanent 70 percent level within three seasons. According to the proposed rules, teams may under certain circumstances be allowed the flexibility to spend up to about $10 million above the ratio, provided they have healthy balance sheets and have not breached regulations before", writes The New York Times.
